Note: DX Engineering is constantly upgrading information and developing new products to
enhance your amateur radio experience. Please check the DX Engineering web site for the latest information: www.DXEngineering.com
The Hustler® Antenna Company introduced this product over 60 years ago, with little attention to maximizing performance. It was designed to be an easy-to-install antenna with minimal grounding, which provided easy - or no - tuning and wide bandwidth but mediocre performance.
DX Engineering decided to take this popular product and show how its performance could be greatly increased by proper installation, including the addition of an adequate radial ground system. This results in lowering the resonant frequency, and also altering the impedance at resonance. Hence - the need to adjust the traps, which was not “allowed” by the manufacturer, and the possible addition of a shunt coil at the feedpoint.
You can install the antenna according to the New-Tronics instructions and make some contacts with little attention to ultimate performance. Our BTV Guide takes you into areas which result in departing from the simple installation and the need to make more adjustments than originally described. That is the reason we designed the tilt base, for easy raising and lowering between adjustments.
The overall experience should be an effort which started with an inexpensive trap vertical, and finished with a high performance antenna installation providing very satisfying results.

Over 60 Years Ago!
The Hustler® HF Base Four Band Trap Vertical antenna was a new concept in 1959. This unique
multi-band antenna with an exclusive low-loss trap design was developed and introduced to
Amateurs by Hustler, Inc. of Cleveland, Ohio, offering quarter-wave antenna performance for 40, 20
15 and 10 meters , but requiring no band switching!
Later, the Hustler® Four Band Trap Vertical, known around the world as the 4-BTV, was made
available with an 80 meter resonator, and the 5-BTV was born. When the Amateur bands expanded
in 1979, the last of the series offerings designed by Hustler®, the 6-BTV, added 30 meters, for an unequalled vertical antenna. Since 1985 the New-Tronics Antenna Corporation in Mineral Wells,
Texas, has been making high quality antennas for HF, VHF and UHF Amateur and Commercial
customers, including the “Hustler® BTV Series”.
Since 2003, DX Engineering has offered Hustler® Antennas and has developed a complete system of
innovative accessories and Add-On Kits specifically for the Hustler® BTV series. Amateurs now
have the choice of complete Hustler® BTV Series High Performance packages for their HF needs,
including the ability to turn their Hustler® into a “9-BTV” covering all bands 80 through 10 meters.
DX Engineering joins New-Tronics Antenna Corporation in celebrating over 60 years of service with
the famous Hustler® HF Base Four Band Trap Vertical – The Hustler® 4-BTV.

Hustler® BTV Antennas
The Hustler® 4-BTV is a four-band trap vertical antenna providing an omni directional pattern. The 4-BTV is designed as a self supporting vertical to provide optimum performance on the 10, 15, 20 and 40 meter bands. This antenna is designed for installations with restricted space. The Hustler® 4-BTV is approximately 19 feet tall. It can also be adapted to operate on the 75/80 meter band by adding the RM-80S resonator and the 4457-1 three blade spider assembly on top of the 4-BTV. If the 75/80 meter resonator is attached to the 4-BTV, it may be desirable to guy the antenna above the 20 meter trap with small diameter polypropylene rope.
The Hustler® 5-BTV is a five-band trap vertical antenna. This antenna includes the RM-80S resonator and the 4457-1 three blade spider assembly. The 5-BTV is designed to provide excellent performance on the 10, 15, 20, 40 and 75/80 meter bands. The Hustler® 5-BTV is approximately 24 feet tall.
The Hustler® 6-BTV is a six-band trap vertical antenna. The 6-BTV is designed to provide excellent performance on the 10, 15, 20, 30, 40 and 75/80 meter bands, using four traps and the RM-80S resonator. The design of the 6-BTV is sleek, with no capacity spiders and is approximately 25 feet tall.
The Hustler® BTV antennas provide automatic electrical selection of the bands through the use of optimum Q traps, which are individually and precisely tuned at New-Tronics.
The traps are parallel tuned circuits which provide efficient isolation between the vertical sections, permitting multi-band operation. Efficient operation over the many ham bands at good SWRs is possible in a proper installation.
The Hustler® BTV antennas were designed to provide optimum performance from both an electrical and mechanical standpoint. Mechanically, this antenna boasts a heavy duty base and heavy duty aluminum tubing. The mechanical assembly is accomplished with all stainless steel hardware. The use of clamps permits re-adjustment if necessary, and allows tuning of each band. The mechanical construction is such that guying is not ordinarily needed.
The performance provided by the Hustler® BTV antenna is better than any other antenna of this type. Broad banding is such that one setting permits both phone and CW operation on most bands.
The antenna provides a nominal 52 Ω base impedance when installed and tuned according to
instructions. The radiation efficiency is equivalent to, or greater than, other trap verticals.

WARNING!
INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS
Warning: Do not locate the antenna near overhead power lines or other electric light or power
circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death.
Overhead Power Line Safety
Before you begin working, check carefully for overhead power lines in the area you will be working. Don't assume that wires are telephone or cable lines: check with your electric utility for advice. Although overhead power lines may appear to be insulated, often these coverings are intended only to protect metal wires from weather conditions and may not protect you from electric shock
Keep your distance! Remember the 10-foot rule: When carrying and using ladders and other long tools, keep them at least 10 feet away from all overhead lines - including any lines from the power pole to your home.
Basic Tools Required

Site Selection
Install your new vertical antenna a minimum of 20 feet away from buildings, wires,
metal fences, downspouts and gutters. Centering a vertical antenna in an open area is the best option. Installing the antenna near a wooden fence or on a wood post is okay as long as there is no metal within 20 feet of the antenna.
Installing the antenna on a metal mounting pipe or a wooden post that is set in concrete
is okay. Since the radial system wires create the efficient ground return for RF currents, direct earth grounding of the support post or a ground rod is not required at the antenna.
Select a mounting location clear from power lines, structures and other antennas by a minimum of 40 feet (30 + 10 foot safety rule). Consider overhead power lines, utility cables and wires. The further away the vertical is mounted from local noise sources or other metallic objects, which can re-radiate noise and affect the tuning, radiation pattern and SWR, the better. Determine the direction you want the antenna to pivot and make sure there is adequate clearance (at least 30 feet).
Mounting Pipe
The mounting support may be a galvanized metal pipe or thick wall steel tube from 1 inch to 1-3/4 inches outside diameter (OD) when using just the Hustler® bracket, and 1 inch to 2 inches OD when using the Tilt Base. A thick-walled steel pipe with a minimum thickness of 1/8" (1/4" preferred) should be used. The standard 1-1/2" galvanized water pipe (with its 1.9" OD) is just fine for this application and can usually be found at your local home building supply store. A four to six inch wood post can also be used for mounting.
Use a thick-walled galvanized steel mounting pipe approximately 6 feet long. This will allow approximately 4 feet to be below ground and 20-23 inches above ground.
The height of the mounting pipe above ground level of 20-23 inches will allow you to do either a basic installation, or an enhanced installation by adding the DX Engineering optional items described in this detailed manual. In some cases ham operators have done a basic installation, and then added the DX Engineering optional items at a later date to enhance their operation. Thus, the length of mounting pipe above ground is 20 to 23 inches.
For permanent mounting, use a post-hole digger to make the hole deep enough to accommodate approximately 4 feet of pipe and a couple inches of gravel at the bottom for drainage. Set the pipe on the gravel, use the pre-mix concrete to fill around the pipe, adding water and mixing as you fill (or mix the concrete first, depending on the type you purchase), then pour the concrete in the hole. Fill the hole until the concrete is level with the ground around it. Use a level as you fill the hole to be sure the pipe is vertically straight. Allow to set overnight (or longer).
- 10 -
Your location, landscape and ground conditions may require different mounting solutions in order to have the steel mounting pipe and the vertical antenna in a secure position. You may also attach the Tilt Base to a 4 to 6 inch wooden post at the location you intend to use the antenna, making sure the unit is securely mounted.
Using a cyclone fence is not recommended for a vertical antenna support or being used as a radial system. Poor RF connections and the presence of high levels of noise that are inherent on metal fences make them an undesirable mounting location for any HF vertical antenna.
Note: Steel, rather than aluminum, is much more suitable for mounting in concrete. Aluminum
will corrode due to incompatibility with the materials used to make concrete.
Concrete or No Concrete – That is THE Question
The original Hustler® BTV installation manuals call for the ground mounting pipe to be driven
into the earth with the specific wording “Do not use concrete. Do not dig a hole and bury the mast. It must be driven in.” The reason for this recommendation is so that installations with few
or no radials will be able to make use of the direct contact between the mounting pipe and the earth to collect and distribute antenna currents.
Unfortunately, the soil and a steel pipe usually do not provide efficient RF conduction. Therefore, the use of ground radial wires are recommended for all quarter-wave ground mounted HF antenna, to improve efficiency and performance dramatically.
Also, a driven or pounded pipe may be used on any ground-mounted vertical antenna installation, regardless of the number of radials used.
DX Engineering recommends using a concrete base, as shown on page 9, when a high performance installation with many radials is planned. The reasons that a concrete base is recommended:
1. It is easier to make sure that the mounting pipe is vertical when it is braced for installation with concrete. Pounded pipes can develop a lean or hit a rock while being driven into the ground, which could result in a leaning antenna.
2. A steel pipe or tube in concrete will last much longer than in soil, especially in certain types of soil that will corrode steel more quickly.
3. Concrete is not an insulator for a steel pipe, as the hardened but moist concrete is a good conductor from the steel to the soil for grounding purposes.
4. A ground surface wire radial system offers far more efficient means to collect and distribute surface RF currents than a single pipe in the soil, so a pipe in concrete is okay when using many radials.
- 11 -
Coaxial Cable to Mounting Pipe
The coaxial cable should be routed from your radio room to the base of the antenna system and be buried below the radial system you will be installing.
PVC Conduit pipe may be used to house the coaxial cable for enhanced protection of the coax cable. Or direct bury coaxial cable can be used. Bury the cable 4" to 12" below ground level.

Get the Best Performance From Your New Quarter-Wave Vertical Antenna
To be certain to get optimum performance from this vertical design, please assemble and install your new antenna according to these DX Engineering Assembly and High Performance Installation Instructions. These instructions are intended to replace those originally supplied by the manufacturer. The Hustler® BTV series of antennas is manufactured by New-Tronics Antenna Corporation, Mineral Wells, Texas.
By following these instructions you will be able to take advantage of all of the performance that your Hustler® HF Multi-Band Vertical has to offer. Here are a few facts about the HF quarter-wave vertical antenna:
For best results, plan for a ground-mount installation with many radials. Engineers and
Amateurs “in-the-know” install a complete ground radial wire system to significantly improve quarter-wave vertical antenna performance for transmitting and receiving. Use copper wire. Do not use grids, mesh fence material or steel which are known to be poor
performers especially for the long term. They can become noise radiators where the wires cross in the mesh pattern.
Mounting this antenna without radials results in average to below average performance and
only local or medium range contacts. Due to RF ground losses, a vertical installation with no radials or only a few radials will have drastically reduced efficiency. On those installations, even though a wider frequency range of low SWR may result, that is a very poor trade-off for an antenna system that offers performance.
Any HF vertical mounted a few to many feet above ground with only a few radials suffers
virtually the same ground losses as a ground mounted vertical with a few radials. This
- 12 -
manual shows you how to plan and install ground radials for better antenna performance and gratifying operational results in almost any situation.
Height above ground is not a requirement for HF Verticals. Unlike horizontally oriented
antennas, ground mounted vertical antennas used for HF sky wave communications only require a radial system for performance. If an HF quarter-wave vertical antenna is elevated, then it requires resonant, quarter wavelength, tuned radials to be efficient and functional. Safer ground-mounted installations can produce results far superior to elevated HF verticals with a few radials.
For low-angle performance, a horizontal antenna requires height, and if it is directional, may
not be able to be rotated, or it requires a tower and rotator. In comparison, an omni­directional HF vertical installed with many radials offers an excellent performance-to-cost value.
Some Brief Words on Ground Mounting, Elevated Mounting, and Radial Wires Ground Mounting
There are multiple ways to install a Hustler® BTV antenna. The most efficient way is to ground mount the antenna, keeping clear of any metal objects and using a good ground radial system.
Ground mounting your quarter-wave vertical antenna will produce significantly improved long range results when your installation includes a good ground-level radial wire system. Seven decades of experiments show that ground mounting with many radials is your best choice.
Safety is another important consideration when comparing ground mounting to roof-top or elevated mounting of your quarter-wave vertical. The DX Engineering Tilt Base offers a safer and easier ground mounted installation. One person can walk-up and tilt-down the antenna for adjustments without a ladder. The new, more versatile Tilt Base models are also helpful when high winds are expected. Order the DXE-TB-3P or the DXE-OMNI-TILT-P1 tilt
base for your Hustler® BTV.
Elevated Mounting
You may also elevate the Hustler® BTV antenna. However, when elevating the antenna the radial system becomes more difficult to deploy in that you need specific length radials that must also be elevated, running symmetrically away from the feedpoint.
In some situations, an elevated or roof-mounted vertical installation is the only option. Resonance­tuned radials must do the job of collecting RF currents. Imagine all of the quarter-wave resonant length wires attached to the base of the antenna, spreading radially (away from the base of the vertical in all directions). For best DX performance, these radials should slope down from the elevate vertical at a 45 degree angle. You can connect the ends of the long radials to support poles or trees. Use the same care as you would for a dipole antenna, keeping the ends insulated and clear of any metal. We recommend four resonant radials per band to enhance low angle radiation. More information on planning and installing the elevated quarter-wave vertical appears later in Chapter 9.
- 13 -
Radial Wires
Radials: Probably THE most important item, for not only the Hustler® BTV, but any ground mounted quarter-wave vertical antenna system are the radial wires. Lack of radial wires causes a
serious compromise to performance.
Will the antenna work without radial wires? In most cases, yes - BUT - it will work at a much lower efficiency in both transmit and receive. Some hams who tried the 'no radial' method and later added a good radial system were very surprised in the difference it made with enhanced transmit efficiency and the ability to receive many more weak signals. The importance of a good radial
system cannot be stressed enough.
Radials are easy to install and the following section outlines the easiest and most efficient way of installing radial wires that will withstand a powered grass mower and provide your antenna with the best possible radial system.
How To Put Radial Wires Down Without Digging
The best time to do this is early spring but it can be done other times, as well. I have even done it in the fall and had good success.
The idea behind this is to get the grass of your lawn to grow over the radials and protect them from the mower.
First, mow the grass pretty short in the areas where you will be laying the radials down. Notice, I didn't say "scalp" it. Just lower the mower until the grass is about 1 inch long after cutting. Readjust the height of the mower back to normal and put it away.
Next, connect the radials to the Radial Plate with wire terminal ends (which you can get at DX Engineering along with the radial wire) and stretch them out while arraying them evenly around the antenna. Some AM broadcast engineers tell us that the radials should be as long as you can make them up to about 1/2 wavelength. If you can only do 1/4 wave or 1/8 wave in
certain directions then do that and don’t worry about it. You
will be surprised how much better your vertical will work.
After you install 20 to 40 radials and see how much better your antenna performs you will have an urge to put in more of them. Don’t resist. More really is better.
Starting from the antenna end of the radials, and about every 3-4 feet, hold the wire down with a Steel or Biodegradable Radial Wire Anchor Pin while pulling the radial out from the antenna to keep it taut. Push it in as far as possible to get the
- 14 -
wire as close to the grass roots as possible. I typically use a rubber mallet to drive it home. If the radial wire is sticking up any place due to uneven ground or the wire is loose just put another staple there. The idea is to get all parts of the wire down as close as possible to the ground so that the grass can grow over it.
When you finish the last radial, your job is done. Mother Nature will do the rest. If you have done this in the early spring, the grass will grow up, surround the wire and pull it down firmly along its full length. If you do it in the fall after the grass has stopped growing, it will happen the next spring. This will be done so completely that in a few weeks you will have to actively look for the radials to see them.
Your mower will miss them completely, too; but you and your contacts will hear them right away! 73,
Paul, NO8D
Note: Radial Wires shown above have Red insulation so they would show up in the
photographs. DX Engineering Radial Wire has a relaxed Black PVC insulation.
Radial System Considerations
The performance of any quarter-wave vertical antenna, multi-band or single band, is completely dependent upon the quality of its radial system. A few local or medium range contacts may be possible using a minimal installation without radials. However, you will get more consistent results and much better performance with a complete radial system. The radial system required depends on whether it is for a ground-mounted or a roof-mounted vertical and on the number of radials you can install.
Many amateurs enjoy excellent quarter-wave vertical performance with only 20 to 30 radials. On ground-mounted quarter-wave verticals, the length of the radial wires is not critical. They can be as short as one-eighth wavelength, but one-quarter wavelength radials on the lowest band of operation are typical. Long lasting and high-efficiency radial wire connections are easy to make using the patented stainless steel DX Engineering DXE-RADP-3 Radial Plate. Use the radial plate for a simple and neat way to install as many ground radial wires as you wish. At a minimum, 20 radials, each 32 feet long, may be used with this antenna. For the best performance on 80 and 40 meters with this antenna, installing 30 to 60 radials each 65 feet long is highly recommended. At a minimum, 20 radials each 32 feet long may be used with this antenna. But, installing many more radials helps overcome unknown poor soil conditions, improves efficiency and ensures the best performance possible from the BTV antenna. Radial Wire that is 14 gauge stranded copper with black relaxed PVC insulation wire is suggested for longevity. DXE-RADW-32RT or 65RT Radial Wire Kits are available. The relaxed black PVC insulated 14 gauge stranded copper wire in our Radial Wire Kits is easy to handle and will last far longer than bare wire or wire mesh.
- 15 -
Why is such an extensive array of radial wires necessary? Simply put, it is the best way to increase your signal! The entire radial system must collect and carry currents equal to those flowing in the vertical section of the antenna. The ground-mounted vertical antenna needs many radial wires to prevent your RF power from being absorbed by the "lossy" ground. Even if your radials cannot run in all directions, you still get improved signals and prevent ground losses by installing as many symmetrically spaced radials as you can. You may use wires of any convenient length. Just run your radials in as many directions as you can, straight away from the antenna base taking care not to zig-zag, bunch or cross over other radial wires. Radials by definition run in all directions, NOT parallel, NOT zig­zags, NOT crossing over each other. Run your radial wires in a spoke pattern.
Install your coaxial cable under the radials, at least a few inches in the ground, to minimize coupling between the radials and the coaxial cable shield. Additional decoupling the feedline can be effectively accomplished using a DX Engineering current choke instead of coiled coaxial cable, to reduce RF feedback (RFI).
To avoid damage from radial installation and for proper RF decoupling, the coaxial cable should be buried several inches under the radial system.
Performance of the antenna is directly proportional to the number and length of radials.
Many short radials are better than a few long radials. The stainless steel DX Engineering DXE-RADP-3 Radial Plate makes it easy to attach long-lasting radial wire connections.
You don’t have to dig! Radial wires disappear under the grass
when installed with DX Engineering steel or biodegradable anchor pins.
DO NOT bother to cut ground radials to resonant lengths
because they are detuned by the ground. It is best to install many radials that are all the same length or lengths that fill a small irregular space.
Radial wires should run in all directions straight from the base
feedpoint of the antenna. Ground radials cannot be bunched together for any length. If your radials cannot cover 360 degrees, that is okay. The antenna performs nearly the same with an equal number of radials squeezed into directions that cover smaller arcs.
Plan to install at least 20 radials at 32 feet each using DX Engineering Radial Wire Kits. However, improved performance is accomplished using 32 to 60 radial wires up to 65 feet in length.

Assembling Vertical Aluminum Antenna Sections & Element Clamps
Note: JTL-12555 Jet-Lube™ SS-30 Anti-Oxidant must be used between all antenna element
sections. Jet-Lube™ SS-30 is an electrical joint compound to affect a substantial electrical connection between metal parts such as telescoping aluminum tubing or other antenna pieces. It ensures high conductivity at all voltage levels by displacing moisture and preventing corrosion or oxidation.
When assembling any telescoping aluminum tubing sections you should take the following steps:
1. Make sure the edges are smooth and not sharp. Deburring may be necessary, since burrs and shavings can occur on seams as well as edges. All surfaces need to be completely smooth to allow easy assembly of tubing sections.
Caution
Aluminum tubing edges can be very sharp.
Take precautions to ensure you do not get accidentally cut.
The raised particles and shavings that appear when the aluminum tubing is machined are referred to as burrs, and the process by which they are removed is known as deburring.
Deburring is a finishing method used in manufacturing. Aluminum tubing is machine cut on
both ends and machine slit as needed. Although Hustler® manufactured aluminum tubing is machine cut, you should further assure that there are no ragged edges or protrusions.
Use the DXE-22600 Deburring Tool with Extending Handle and DXE-2211 Extra Blades
for this operation.
2. Clean the inside of the aluminum tubing to clear out any dirt or foreign material that would cause the aluminum tubing sections to bind during assembly. Do not use any type of oil or general lubricant between the aluminum tubing sections. Oils or general lubricants can cause poor electrical connections for radio frequencies.
- 18 -
3. Clean the outside of the aluminum tubing to clear any dirt or foreign material that would cause the clamps to malfunction during assembly.
4. JTL-12555 Jet-Lube™ SS-30 Anti-Oxidant must be used between all antenna element sections. Jet-Lube™ SS-30 is an electrical joint compound to affect a substantial electrical connection between metal parts such as telescoping aluminum tubing or other antenna pieces. It ensures high conductivity at all voltage levels by displacing moisture and preventing corrosion or oxidation.
5. When assembling the aluminum tubing sections, ensure the area is clear of grass, dirt or other foreign material that could cause problems during assembly of the closely fitted telescoping sections.
Assemble the vertical sections in an area that is flat and has sufficient room for the length of the antenna during assembly. The traps have a plug in the ends, these plugs are not removed during assembly.
Assembly is easier if the tubing sections are pre-marked. A dark color felt-tip marker works well. Locate the hardware pack containing the element clamps. Refer to the following 4-BTV, 5-BTV or 6-BTV assembly instructions, depending on your antenna,
for element clamps, tubing and trap placement. Slide all the clamps over each section before putting them together. You can lightly
tighten the clamps just below the slits in each section to hold them until needed. Align the clamp screws on each section to face the same direction. At final assembly, body of the clamp should be positioned between the slits in the
tubes and 1/8" from the edge of each tube as shown to the right. Making sure dirt or grass does not adhere to the sections to be joined. The body of the
element clamp is positioned between the slits and tighten securely. The following charts show the suggested starting measurements for the 4/5-BTV and 6-BTV
antennas. Note the charts show different measurements for various installation methods.

Prepare the three bladed spider for the 5-BTV. Carefully bend the three blades as shown. The spider mounts just below the 80 meter resonator.
80 Meter Resonator and Whip Installation for the 5-BTV and 6-BTV
Using the supplied Allen Wrench, loosen the two Allen set screws far enough to allow insertion of the whip antenna about 4" beyond the set screws as shown below. Snug the Allen set screws in place to hold the whip in place. During tuning, you will be making adjustments to this length.
Install the Hustler® 80 RM Resonator to the top of the 5-BTV or 6-BTV in the threaded rod that is protruding from the top tube. The whip will be trimmed for the desired frequency during the tuning.
If you desire to have two frequencies that are far apart (CW -vs- SSB), you may want to have two whips One whip cut for the lower frequency in the CW area of the band, and another whip cut for the higher end in the SSB area of the band (Part Number HSR-49-04-80S from DX Engineering).
Tuning of the 80 Meter resonator will be covered in the Chapter 7 of this manual.

Hustler® Base Assembly
The Hustler® Base Assembly (HSR-4098-1) is pre-assembled from the factory. The following
diagram shows all the parts, including the parts that are used for basic mounting on a 1 inch to 1-3/4 inch OD mounting pipe using the included U-Bolts from New-Tronics.
- 27 -
Optional Reinforced Lower Tube Assembly
The DXE-RLT - Reinforced Lower Tube Assembly for the Hustler® 4-BTV, 5-BTV or 6-BTV Vertical Antenna is a custom made aluminum, sleeved, double wall, tube assembly that replaces the first six foot aluminum section of the Hustler BTV Series antenna. The reinforced tube assembly adds strength to the overall antenna which will help with wind survivability.
Why replace the existing lower section? Why not just slip another tube over my existing tube? Any Hustler BTV antenna may have some slight bend in the lower first 6 foot section of the antenna. The tight tolerances between DX Engineering sizes of aluminum tubing are such, that even a slight bend in one of the tubes may be enough to prevent close tolerance tubes to be sleeved over each other. The ready-to-use DXE- RLT solves that issue. Additionally, this double wall assembly is pop-riveted in place making the new tube assembly easy to install.
The use of JTL-12555 Jet-Lube™ SS-30 Pure Copper Ant-Seize is recommended to be used between all aluminum antenna sections to help ensure complete RF connections and to help keep out any moisture.
Using a felt tip pen (or equivalent) draw marks on the 10 meter trap and the base assembly where the existing first 6 foot section ends.
Loosen the band clamps and remove the existing first (bottom) 6 foot section of the BTV antenna and replace it with the DXE-RLT Reinforced Lower Tube Assembly as shown in the picture to the right. The reinforced tube (shorter tube) is toward the bottom of the antenna.
Align the marks you made earlier on the 10 meter trap and base section from the previous lower tube position with the new tube assembly and tighten both upper and lower element clamps. There is no re-tuning required and your antenna should have the same performance prior to replacing this lower 6 foot section.
As with all vertical ground mount antennas, it is still recommended that the antenna is guyed. Especially in areas subject to high gusts, sustained wind areas, ice and other extreme weather conditions.
- 28 -
Mating the Vertical Sections to the Base Section
CAUTION: Attempting final assembly without proper precaution can be dangerous.
You should have someone help you steady the vertical antenna sections during
mating with the base section.
Slip the completed antenna sections onto the base section as shown below. Set A1 dimension to the required spacing as shown in the charts below. Tighten the element clamp.

Installing Radials & Feedline on the Hustler® Base
If you are connecting the radial wires directly to the antenna base, use the following drawing showing the hardware required. This diagram also shows connecting the feedline direct to the Hustler® base using the supplied lugs for coax connections.
For radial wires, the better alternative is to use an optional DXE-RADP-3 DX Engineering
Radial Plate.
Additionally, the feedline can be connected using other methods using DX Engineering custom made feedline options as shown in Chapter 6.
- 30 -
Coax RF Choke
Hustler® recommends a wound coax type of choke to help prevent RF feedback into the radio room. The following diagram shows the coax cable choke system which offers modest performance on some bands. See further information about the DX Engineering feedline choke.
The better alternative is the optional DX Engineering DXE-MC-20-FC Feedline Current Choke which is specifically engineered and manufactured to help eliminate RF feedback from a resonant vertical antenna. More information on the Feedline Current Choke can be found in Chapter 6.
Basic Tuning
In a few basic installations adjustment of the antenna to obtain the lowest SWR may not be necessary. However, a broad, low SWR over an entire band or all bands is an indication of poor efficiency. If at all possible, the addition of radials will improve performance as detailed in Chapters 4 and 6. For ground mounted installations the length of radials is not critical and they cannot be used to change the tuning. Elevated system radials are resonant and they need to be pruned to lengths for the bands that are used.
Slight adjustments of SWR minimums can be made by shortening or lengthening the starting dimensions between the antenna tubing sections and the traps in performance installations. These adjustments may not provide enough changes and you will have to proceed with Trap Calibration for additional tuning instructions in Chapter 7. Do NOT cut the antenna tubing.

The installation and tuning is breeze with the patented Tilt Base. Your radial wire attachment is made easier with the Radial Plate mounted slightly above ground. The Bulk Radial Wire kit allows you to cut your symmetrically spaced radials to fill your space. Your radial wires do not need to be resonant lengths on the ground, and if they cannot run away from the antenna in all directions, that is okay! The antenna performs virtually the same as when radials are run in all directions. Many radials, even if they are short, are better than few long ones.
Both accessories are attached to your antenna mounting pipe or tube with the adjustable Stainless Steel V-Clamps.

Attaching Ground Radial Wires to the optional Radial Plate
Using the 20 sets of supplied 1/4" stainless steel hardware (Bolt, Flat Washer, Star Washer, Split Washer, Nut) connect the optional ground radial wires to the DXE-RADP-3 Radial Plate as shown in the drawing below. Additional hardware kits are available (DXE-RADP-1HWK) that contain 20 sets of Radial Plate Hardware.
At a minimum, 20 radials, each 32 feet long, should be used with the Hustler® BTV antenna. DXE- RADW Radial Wire, a 14 gauge stranded copper with a black relaxed PVC insulation wire, is suggested for the best results. Better results are obtained with 30 to 60 radials, each 32 feet long.
The wire radials should placed as symmetrically as possible straight from the feedpoint around the vertical antenna and spaced evenly, regardless of how many radials are used. Do not cross, zig-zag or bunch any radial wires as this nullifies their effectiveness. If you have limited space, put in as
many straight radials as you can. The radials must be connected to the shield of your feedline. The DXE-RADP-3 Stainless Steel Radial Plate is an ideal optional item which provides an excellent system for attaching radial wires to your vertical antenna system feedpoint.
Radial wires can be laid on the roots of the grass using DXE-STPL Radial Wire Anchor Pins to hold them down. Using enough staples will ensure the wires will not be snagged by mowers, people, or animals. As described
earlier, the grass will quickly overgrow the radials and it will be virtually impossible to see them.
There are optional DX Engineering Radial Wire Kits available. DXE-RADW-500K/BD contains a 500 foot spool of 14 gauge copper stranded wire with black PVC insulation, 20 Terminal Lugs and 100 Steel or Biodegradable Lawn Staples. The DXE-RADW-1000K/BD Radial Wire Kit contains a 1,000 foot spool of 14 gauge copper stranded wire with black PVC insulation, 40 Terminal Lugs and 200 Steel or Biodegradable Lawn Staples. RADW-20RT, -32RT or -65RT contain 20 each radial wires with 1/4" terminal attached. These kits come in 20 Ft, 32 Ft, or 65 Ft lengths.
Depending on the number of radial wires used, space them out evenly around the Radial Plate. The Radial Plate will accommodate up to 60 radial wires (60 laser drilled holes), or up to 120 radials if doubled up.

Make sure the Tilt Base and optional DXE-RADP- 3 Radial Plate are oriented correctly for the direction you wish to tilt the antenna. See page 35 which shows the tilt action.
Tighten the clamps evenly so the length of the exposed threads is approximately equal. Any clamp should be tightened evenly from side-to-side with an equal amount of thread above each nut.
BTV Antenna Base Section to the optional DXE-TB-3P Tilt Base
Using the new hardware included with DXE-TB-3P Tilt Base, install the four hex head bolts, four flat washers, four split washers and four hex nuts in the
BTV Base Section as shown to the right.
Place the BTV Lower Base Section into the holes of the mounted Tilt Base and loosely install the Tilt Base mounting hardware shown to the right. Leave the flange nuts and Nyloc nuts slightly loose.
Using a wrench or nut driver, securely tighten the two Nyloc Nuts at the bottom of the Tilt Base. Then loosen them one-half turn each. This will allow proper movement of the Tilt Base while raising or lowering the antenna. It is not necessary to tighten these nuts more securely unless further tilt operation is no longer required. They should not be loosened more than one-half turn at any time.
- 36 -
Testing the DXE-TB-3P Tilt Base
Test the tilt function to ensure proper clearances. Standing in front of the Tilt Base, lift the antenna base section, slide it to the right, and let it down slightly until the lower outside bolt is resting in the pivot point. Then slowly tilt as shown in the picture below. Make sure when you are tilting the antenna to lift, slide to the right, and then tilt. Be careful to keep the pivot bolt resting in the pivot point. Reverse the process when raising the antenna.
It is important to note that the lower, outside bolt becomes the pivot point while raising or lowering the antenna. This pivot bolt MUST be retained in the pivot point. It seems natural to push the antenna toward the Tilt Base while raising. Push up while raising, but not toward the base since this could cause the pivot bolt to lift out of the slot and allow the mechanism to bind up and bend the lower bolts. Keep the antenna parallel to the Tilt Base when raising or lowering to prevent the pivot bolt from jamming.
The Tilt Base is not made to support the whole antenna by itself when tilted. When the antenna is tilted over, ensure you have some sort of table, stand, or saw horse to set the antenna on to aid in supporting the weight. When the antenna is in the upright position, ensure the mounting hardware (flange nuts and Nyloc nuts) are tightened.
Note: A pair of sawhorses or ladders should
be used to support the vertical sections during assembly with the tilt-base and whenever the vertical is tilted down. Do not allow the Tilt Base to support the entire weight of the antenna when horizontal.

DXE-OMNITILT-1P OMNI-TILT™ Tilt Base (included in the -P2 Kits)
The DX Engineering OMNI-TILT Vertical Antenna Tilt Base is a new design incorporating features that make this Tilt Base a
must have’ for all types of vertical antennas.
Custom made from laser cut 1/8” thick Stainless Steel for strength
and durability. All of the hardware used in the OMNI-TILT Base is Stainless Steel to ensure long and dependable service.
The DX Engineering OMNI-TILT is safe to use and is available with a wide range of optional mounting hardware to maximize the use of this tilt base with all types of vertical antennas.
The OMNI-TILT may be used with the Hustler BTV series antennas which both uses the optional DXE-TVA-HWK Trap Vertical Mounting Hardware kit. Additionally, the OMNI-TILT may also be used with other vertical antenna or mast mounting schemes depending on the mounting hardware chosen to correspond to the diameter of pipe (1-1/4” to 2-1/2” diameter) being used.
Refer to the DXE-OMNITILT-1P manual for details on the assembly of the basic OMNI­TILT™ Tilt Base.
OMNI-TILT™ Tilt Base Tilt Action
1. To tilt downward loosen the top Nyloc Nuts to allow the Flanged Nuts to be loosened approximately 1/2 to 1 turn.
2. Grasp the antenna base (or mounting pipe) that is bolted to the OMNI-TILT base and lift until the upper bolts on the front plate are out of the grooved area on the tilt base rear plate.
3. Slightly tilt until the front plate can bet set downward into its resting place.
4. Carefully walk the antenna (or antenna and mounting mast) downward.
5. Use of a chair or saw horse to support the antenna so it remains level or protruding parts of the antenna do not hit the ground when tilted down is suggested.
Reverse the above step to raise the antenna (or antenna and mounting mast). Once raised and the front plate is in the grooved area and fully seated, tighten the flanged nuts. The Nyloc nuts can then be tightened against the flanged nuts to prevent them from loosening from wind vibration.

A second method that may be used is the connection of a pigtail from the feedline connection on
the Hustler® BTV base section to the Radial Plate using a DXE-8X19-RT 19" Pigtail for the Hustler® BTV Base to PL-259 along with a DXE-UHF-FDFB-KIT SecureMount™ Bulkhead Fitting, SO-239 Socket, Silver Plating, PTFE Insulation to connect to the Radial Plate.
This cable makes connecting the Hustler® BTV antennas to 50 ohm coax easy!
Utilize this pigtail to convert the Hustler® BTV base connections to a PL-259 connector. Then, use a DXE-UHF-FDFB-KIT SecureMount™ bulkhead connector to mate the pigtail to your feedline. Done! The pigtail and bulkhead connector are ideal for use with the DXE-RADP-3 radial plate. This pigtail is not required if you order the optional DXE-MC20-FCM Feedline Current Choke & shelf for connection to the base of the Hustler® BTV series antenna. It is also not required if you use the DXE-AOK-DCF SO-239 add-on kit for direct connection of your coaxial cable feedline to the BTV antenna.
The DXE-MC20-FCM Feedline Current Choke and Mounting Shelf
In cases where you have RFI in the shack, the DXE-MC20-FCM DX Engineering Feedline Current Choke may be the answer. The choke stops unwanted RF from using your coaxial cable and either a radial or a radiating antenna.
The shelf and mounting bracket are installed on the mounting pipe approximately 1/4" above the Radial Plate using one optional DXE-SSVC-2P V-Clamp as shown below. The coax cable from
your shack (or transceiver) connects on the other side of the choke (you can’t see that connection in
these photos).

Understanding Trap Calibration
The Hustler® warranty states that adjustment of the traps will void the warranty. As described in this manual, trap adjustment is usually required. When you purchased your Hustler® BTV from DX Engineering, your warranty is safe.
Trap calibration adjustment will NOT void the warranty of a Hustler® antenna purchased from
DX Engineering. The antenna traps will not be harmed by performing this tuning procedure.
Note: For the purposes of these instructions the term “resonance” or “resonant frequency” is
defined as the point of lowest SWR and may be used interchangeably.
A high efficiency quarter-wave vertical requires a good radial system. Installations with few or no radials are inefficient due to high ground losses. These losses are the reason that verticals with no radials or few radials seem to exhibit a great SWR curve, which is a sure sign of an inefficient vertical antenna. Therefore, removal of radials to achieve a lower SWR, or a broader SWR curve, is not a tuning solution. DO NOT attempt to tune the vertical antenna by changing radials in any way.
After Installing a Good Radial System, the Hustler
®
4-, 5- and 6-Band Trap Vertical antennas, as supplied by the manufacturer, will normally resonate at frequencies much lower than desired, and especially when installed on very good soil, saltwater or a metal roof.
Readjusting antenna resonance is easy. The traps were made to be adjustable so that retuning the vertical for in-band resonance is not difficult. The trap sleeve position adjustment may be done the same as on other parts of the antenna. You can loosen the stainless element clamp, make a trap sleeve adjustment and tighten the clamp. Note that a slight movement of the trap sleeve will produce a rapid change in the frequency of lowest SWR. Follow the procedure described below carefully to make large frequency adjustments to any Hustler® BTV HF antenna.
Never Cut the Aluminum Tubing - You cannot properly adjust the frequency of the Hustler® BTV antenna by cutting the traps or by cutting the aluminum tubing above or below the traps.
The right tool for the job - An antenna analyzer is the best tool to use for adjusting any antenna to the target frequency if it is connected directly to the feedpoint. Since that is never convenient, use a six foot piece of 50Ω coaxial cable between the antenna and the analyzer and tune for minimum SWR. Your body can affect the tuning if you are too close to the antenna. If the coaxial cable length is too long, the analyzer SWR measurements may be incorrect.
When adjusting antennas, your primary goal is to move the low SWR point to your target frequency. [Perfect analyzer impedance readings near 50 Ω resistance and X=0 or ± j0 reactance
- 44 -
are not realistic. The frequency where the lowest SWR occurs will likely result in analyzer readings that are not perfect.]
If you only have an SWR or power meter use it at the antenna. Use your transceiver or analyzer and plot a chart of SWR measurements at several frequencies across the range below and above your target frequency, repeating after every antenna adjustment. Starting at a low frequency, record SWR measurements at regular increments higher in frequency to determine where the lowest SWR occurs.
When making antenna adjustments, DO NOT watch a certain frequency hoping for a minimum SWR to appear. Over-adjustment could cause you to miss the “dip” as it passes your target frequency. It is better practice to take enough readings in order to follow the minimum SWR point as you make adjustments so you can achieve low SWR at your target frequency. Make sure you adjust the antenna traps to frequencies that are going to be used, not simply in the middle of the band.
Hustler® Traps
The manufacturer sets the traps to specific dimensions. Since you are optimizing the antenna system using a good radial system, adjustments will have to be made. For reference, the photo below shows the traps as they come from the manufacturer. You should mark spot where the trap lower tube meets the trap sleeve with a felt tip marker. This will help in case you have to go back to the initial manufacturer's settings.
[Note: The dimensions shown may vary due to
manufacturing assembly tolerances.]
In this tuning procedure we'll be talking about loosening the trap cover, loosening the band clamp and adjusting the trap sleeve. The photo to the left shows these parts.
The manufacturer puts a silicone sealant inside the black plastic trap covers. Loosen the band clamp and twist the trap sleeve while holding the black trap cover will loosen it. The silicone that was put in there can be removed so the black trap cover and trap sleeve can be repositioned. Resealing the trap cover may not be necessary, as it grips the trap top tube tightly and the trap sleeve has slits at the bottom for moisture to escape. If you choose to use silicone sealer, be certain it is non-acetic (without a vinegar smell) and it does not contain metal (PTX-82180 - Black RTV
Silicone). You must adjust each trap with the antenna completely assembled – traps cannot be adjusted before assembly. It is not necessary to remove each trap from the larger tubing below it, or measure it, in order to make the trap sleeve adjustment to tune the antenna. The lettered dimensions charted below are only starting points and will normally be changed for fine tuning.

Hustler® Trap Calibration - Resonance Adjustment Procedure
Tune all Hustler® BTVs starting with the 10 meter trap, because any adjustment done there
affects the rest of the antenna, regardless of the number of bands it has.
1. Slightly loosen the band clamp at the bottom of the trap sleeve, NOT the clamp on the
larger tube below.
2. Loosen the trap cover.
3. Adjust the trap sleeve position on the
trap bottom tube. Typical adjustment is to move the trap sleeve downward on the trap lower tube about 1/4 to 1/2 inch reducing the A2 dimension below the 10 meter trap for a shift of +500 kHz.
4. Firmly tighten the band clamp.
5. Reposition the trap cover.
6. Raise the antenna, re-test to find the
new frequency and SWR dip.
7. Readjust (repeat steps 1-6) to move
the SWR dip to the desired frequency.
After you adjust one trap, check all bands before repeating steps 1 though 7 for the other traps in order (15M then 20M then 30M depending on BTV model).
It is not necessary and counter-productive to readjust the spacing (A2, B2, C2 or D2) to the original chart dimension after a trap sleeve adjustment. In some cases, you may need to increase these spaces between the trap sleeves and the antenna sections to allow enough spacing to complete recalibration.
Note: Like other antenna adjustments, trap adjustments are not permanent and can be restored easily. You marked the position of the trap sleeve on the trap lower tube before you started, so returning to the starting point will be simple.
Do not worry if you cannot tune the antenna to the lowest possible SWR of 1.0:1 at your frequency of choice. A minimum SWR of 1.4:1 to 2:1 is acceptable for HF operations, representing a minor RF power reflection.
Your new high efficiency antenna system is now properly installed and tuned and will reward you with years of service.
In some cases if you are still low in the resonant frequency, you may have to adjust A1, B1, C1, D1, E1 in small increments depending on which band(s) is/are effected. If you do make these adjustments, trap calibration may also require some further adjustments.
- 47 -
Tuning the 80 Meter Resonator Whip for the 5-BTV and 6-BTV
An antenna analyzer is the best way to adjust the resonant frequency of an antenna. The RigExpert line of antenna analyzers are ideal equipment for tuning a Hustler® BTV antennas.
Measurements should be made at the antenna using a (10 or 20 ft.) piece of 50 coax between the antenna and the analyzer. If you are too close to the antenna your presence can affect the tuning, if you are too far, the coax length may act as a radial and resonate. Taking readings close to the antenna also eliminates the possibility of a long or marginal feedline influencing the tuning or causing erratic readings. You should tune the antenna for low SWR rather than resonance (X=0) although they are often close or at the same point. Normally, the SWR goes down somewhat and the bandwidth increases once the feedline is reconnected and you measure the SWR at the operating position.
The whip must be trimmed for the frequency desired. The chart below shows good starting points. Using the antenna analyzer will aid in getting the desired resonance. Make small adjustments to the whip length and verify you are going in the proper direction. Use the old adage "Measure twice, cut once".
If you desire to use two frequencies that are far apart (CW -vs- SSB), you may want to have two whips. One whip cut for the lower frequency in the CW area of the band, and another whip cut for the higher end in the SSB area of the band. (Part Number HSR-49-04-80S from DX Engineering) Changing the whip is made easier when using the DX Engineering Tilt Base.

The DXE-VMN-1 Vertical Antenna Matching Network is designed for use on 160, 80 and 40 meter quarter-wave verticals and with the Hustler® 5 and 6-BTV. In some
vertical antenna installations with excellent radial systems, achieving the best SWR on the lower bands may be difficult without some means of adjusting the impedance. The DXE-VMN-1 allows easy adjustment for lowest SWR. The DXE­VMN-1 Vertical Antenna Matching Network will aid in tuning the customer selected
portion of the 80 meter band to the minimum SWR without affecting operation on the other, higher frequency bands.

Chapter 8 - Guying the Hustler® BTV Antenna System

Guying the Hustler® BTV Antenna System
Most verticals need at least one set of three or four guy ropes to survive moderate to high winds. If
you roof mount, you will need two sets of guys, one set near the middle and another high on the vertical. Tie the rope around the antenna just above one of the band clamps. Ultraviolet resistant Dacron/polyester rope is the best choice, such as model SYN-DBR-94. Several other sizes and lengths are also available from DX Engineering. Gentle stabilization is what’s required, not a strong anchoring like a tower would need. For ground mounted vertical antennas of any brand, DX Engineering offers guying kits that include the rope and ground anchors (DXE- GUY100, 200, 400 or 1000-KIT).
Some vertical antenna manufacturers indicate their antennas do not need guying. During times of high winds or ice loading, some of these verticals may sustain damage or fail altogether. With the small amount of effort needed to install a four point guying system, the risk hardly seems worth taking. A four-point guying scheme provides the best mechanical advantage to prevent wind stress, regardless of direction. When using an optional Tilt Base, a four point guying system is recommended because just one of the guy ropes has to be loosened when you tilt the vertical down. The remaining guys help stabilize the vertical in three directions when being raised. The DX Engineering Vertical Guying Kits have been designed to be used with ground mounted vertical antenna systems.
The guying kits are ideal for fixed or portable installations.

Elevated Mounting of the Hustler® BTV
In some situations, an elevated or roof-mounted vertical installation is the only option. Elevated installations are more difficult. In all but certain metal roof elevated installations, resonance-tuned radials must do the job of collecting RF currents. Imagine all of the quarter­wave resonant length wires attached to the base of the antenna, spreading radially (away from the base of the vertical in all directions). For best DX performance, these radials should slope down from the vertical at a 45 degree angle. You can connect the ends of the long radials to support poles or trees. Use the same care as you would for a dipole antenna, keeping the ends insulated and clear of any metal. We recommend four resonant radials per band to enhance low angle radiation. If you must elevate your antenna, Pre-Cut Radial Wire Sets are also available from DX Engineering.
An antenna analyzer is used to make resonant, elevated radials. For the Hustler® BTV series and most other quarter-wave vertical antennas, it is best to start with the highest band, usually 10 meters. Determine the frequency within the 10 meter band where you want the vertical to resonate. Construct two radials, as if you were making a dipole, to resonate on that frequency. Next, make two more radials the same length. Then, connect all four to the base of the vertical or the Radial Plate. Fan them out symmetrically from the antenna.
Using the information in Chapter 7, start with tuning the 10 meter section of the vertical for the lowest SWR on the same frequency as your radials. Repeat this procedure for the remainder of the bands your antenna covers, going from the highest frequency band to the lowest frequency band. In an elevated vertical installation, do not ground the radials, the mast, or the vertical mount. Grounding them will probably detune your resonant radial system!
Be careful - The vertical will be high above the ground, be aware of any overhead power lines that may touch the vertical antenna or radial wires. The vertical should be at least its own height plus 10 feet away from any wires or obstacles so if it falls, it cannot come in contact with electrical power lines (remember the 10 foot safety rule). Contact with power lines can be fatal! Proper guying of your elevated vertical requires planning. Find good guying anchor points before installing your antenna.

The Quarter-Wave Vertical on a Metal Roof
Over the years, many Amateur Radio operators have successfully used a metal roof as the ground plane or radial system for their quarter-wave HF vertical antenna. This is possible with a metal roof on a home, barn, garage, carport, RV, porch and metal sheds or awnings, and even on commercial buildings. The actual height of the metal roof above ground is not especially important for an HF quarter-wave vertical antenna.
In order to take advantage of a metal roof as a ground plane, you cannot elevate a quarter-wave vertical high above a metal roof. The key is that the antenna feedpoint, which is usually at the mounting bracket, should be the same physical level as the metal roof to offer the best ground plane effect.
The feedpoint of the vertical should not be any more than 4 to 8 inches above the roof, even if the mechanical mounting would allow for a higher installation. In other words, raising a quarter-wave vertical antenna many feet above the metal roof does more harm than good with regard to impedance matching and tuning. Mounting the HF quarter-wave antenna at the top of a tall mast, without a feedpoint level radial system, does not function electrically, and is mechanically very difficult. If you must use a tripod for mechanical mounting reasons, use one that is as short as possible. With a tripod mount, you must use a basic wire radial system that emanates from that slightly elevated feedpoint and drapes down over the metal roof to make use of the coupling effect described below. You cannot make a direct connection of the coax shield to the metal, due to the distance of the feedpoint above the metal.
There are two ways that a quarter-wave vertical can be installed on a metal roof or large metal awning as a ground plane.
The potentially less efficient installation uses direct grounding of the coax shield and antenna bracket to the metal roof. This might work well for transmitting and would probably "appear" to work well due to excellent receiving results. However, you may find that you aren't easily heard. This would be an indication that the sections of your metal roof are not well bonded. Remember, we are trying to provide the same low impedance RF current collection and distribution as a ground mounted system of 30, or more, straight copper wire radials that are about one-quarter wavelength long. Just because the metal panels of a metal roof are connected with a bunch of screws or nails, and even when a multi-meter shows DC continuity between the panels, does not mean that you have a good radial system for RF. You can try it and believe that it is working great, but you may not really know how efficient the directly connected metal roof is working for you. Measured at the antenna, a frequency range of over 400 kHz under a 2:1 SWR across and beyond the 40 meter band (7.0 to 7.4 MHz) would be a general indication of radial system or ground plane inefficiency, depending upon the size of the vertical. Conversely, a very efficient ground plane will narrow the SWR bandwidth of a vertical, as narrow as 150 kHz on the 40 meter band on the BTV series antennas.
The preferred installation for your quarter-wave vertical using a metal roof or large awning as your ground plane is to connect the coaxial cable shield to several (6 to 16) insulated radial wires that are placed on, under, or are draped out over the metal roof. The radials must be attached to the antenna feedpoint, never at the bottom of a tall mast or tripod. Capacitive and inductive coupling between the radial wires and the metal roof accomplishes the collection of the RF currents. The number of
- 51 -
these "coupling radials" that you need will vary from one installation to another, but you may need fewer than would be required for a high performance elevated mount or ground mount where there is no metal roof. They may be resonant lengths, unless space is a concern. Many short radials may get the job done for the lower frequency bands, too. In this installation, the antenna mounting bracket, the coax shield, and the radial system may need to be kept insulated from the mast and metal roof, to allow the coupling effect to work properly. Actually connecting the metal roof to the radial system may work better for your installation. This is another example of the fun of HF; where changing a simple electrical antenna connection may dramatically improve your antenna system performance.
Ideally, a quarter-wave vertical is physically mounted in the center of a metal roof ground plane. This would provide the best omni-directional low angle radiation pattern. However, mounting a structurally sound vertical antenna at the center of a roof is not always possible. It is true that mounting the vertical at one end of the roof will affect the omni-directional pattern. However, the signal reduction of a few dB in the direction away from the metal roof, or any very good radial system, will not prevent you from enjoying the low angle pattern and resulting DXing benefits of quarter-wave vertical!
Consider the DX Engineering Feedline Current Choke kit model DXE-MC20-FCM (see page 41), to make up for deficiencies in the metal "ground plane" or radial system. This choke and its properly mounted shelf kit isolates the feedline, balances currents on the system for maximum signals, and offers the additional advantages of reduced noise and RFI/TVI.
You can expect your large area metal ground plane or radial system to make a quarter-wave vertical resonate especially low in frequency (usually on 40 and 80 meters) and exhibit an impedance below 50 ohms at the feedpoint. IF that happens on your system, congratulations! You are the proud owner of a highly efficient quarter-wave vertical antenna system! Now, adjusting the antenna for minimum SWR at the desired frequency and re-matching the feedpoint to the feedline may require some additional adjustments, as discussed in the Tuning the Hustler® section of this manual, including the addition and use of a simple Vertical Matching Network, model DXE-VMN-1.

What Trap Do I Have?
In some cases the trap you have may not be easily identified. During manufacturing, New-Tronics applies a colored label to the trap sleeve, just below the trap cover. 10M = Orange, 15M = Red, 20M = Green and 30M is Blue.
If your trap label is missing, you will have to open up the trap and count the turns of wire on the internal coil. You can re-assemble the trap according to the dimensions in Chapter 7.

Weatherproofing Coaxial Cable Connections
After firmly attaching your existing coaxial cable, the PL-259 and SO-239 should be weatherproofed using rubber splicing tape which is a conformable self-fusing rubber electrical insulating tape. For outdoor use, the Temflex rubber splicing tape should be protected from UV deterioration with an overwrap of electrical tape for all weather applications.
Peel back the protective covering. Tightly wrap the Temflex. When wrapping, stretch the rubber splicing tape up to twice its normal length. Wrap tightly around the coaxial cable and connectors. Overlap each wind of the tape by about 50%.
Use the electrical tape as an overwrap to give the assembly UV protection. Cover the Temflex splicing tape completely.
Lightning Protection - For Any Installation
Proper lightning protection and grounding is a prudent investment for any Amateur Radio antenna installation.
