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.

Installation

Site Selection

Select a mounting location clear from power lines, structures and other antennas by a minimum of 55 feet (45 plus 10 for the 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. When using the Tilt Base, determine the direction you want the antenna to tilt down and make sure there is adequate clearance. There should be sufficient room for a radial system that will extend away from the antenna equally in all directions, if possible.

- 4 -

Mounting Pipe

Use a customer supplied thick-walled galvanized steel mounting pipe at least 4 feet long. This will allow approximately 2 feet or more to be

below ground and approximately 2 feet above ground. A thick-walled steel pipe 1-3/4" OD to 2" OD maximum is required 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. For permanent mounting, use a post-hole digger to make the hole deep enough to accommodate 2 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, then pour 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 straight. Allow to set overnight. 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.

Note: Galvanized steel, rather than aluminum, is much more suitable for mounting in concrete.

Aluminum will quickly corrode due to incompatibility with the materials used to make concrete.

Radial System

At a minimum, 20 radials, each 32 feet long, should be used with this antenna. Using 32 radials at 32 feet long is preferred and highly recommended. The extra radials may help overcome unknown poor-soil conditions, improve efficiency, and ensure the best performance possible from the vertical antenna. Longer radials should be used for improved performance on the lowest frequency to be used if your plans call for 60 or more radials. DXERADW Radial Wire, a stranded 14 gauge copper wire with a black relaxed PVC insulation is suggested for the best results. The wire radials should placed as symmetrically as possible around the vertical antenna and spaced evenly, regardless of how many radials are used. Do not cross 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.

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. Grass will quickly overgrow the radials and they will be virtually impossible to see. An article describing this process is available the DX Engineering website in the Tech Info section. Radials can also be buried just under the surface by using a power edger to make a slit in the soil.

Assembly

The DXE-60VE-1P shipping box contains the vertical tubing element sections, an insulated Uchannel, two 3/8" U-Bolts, saddles with hardware, a backing plate, a Tilt Base, 15 stainless steel clamps, a black vinyl cap, and stainless steel hardware.

Carefully un-box the antenna and separate the various parts. All of the element sections are 36" long. The 2" OD base element section is drilled and has the feedpoint connection installed. The top 3/8" OD section and the base section do not have slit ends. The 2-1/8" OD section is slit on both ends. All the other sections are slit on one end. The vinyl cap for the top element section should be installed after assembly of the vertical is complete.

Jet-Lube™ SS-30 should also be used on all element clamps and stainless steel threaded hardware to provide good electrical contact, prevent galling, allowing easier disassembly and to ensure proper tightening.

Note: The following assembly instructions are based on using a 2" OD (maximum)

Mounting Pipe, with the optional patented DXE-RADP-3 Radial Plate. 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.

Radial Plate to Mounting Pipe

Install the optional patented DXE-RADP-3 Radial Plate on the 2" OD (maximum) mounting pipe using an optional DXE-SSCV-2P V-Bolt Saddle Clamp as shown in Figure 1. Mount the radial plate so you have approximately 1" of space between the bottom of the plate and the ground level. This will allow easy access to install the radial wire hardware. The DXE-RADP-3 Radial Plate comes with 20 sets of stainless steel hardware for mounting the radial wires. Mount the plate as shown in relation to how the Tilt Base. For reference, Figure 7 shows a completed assembly.

Figure 1 - DXE-RADP-3 Radial Plate Installation

Attaching Ground Radial Wires to the Radial Plate

Using the 20 sets of supplied 1/4" stainless steel hardware (Bolt, Star Washer, Flat Washer, Split Washer, Hex Nut) connect the optional ground radial wires to the DXE-RADP-3 Radial Plate as shown in Figure 2. Additional hardware kits are available (DXE-RADP-1HWK) that contain 20 sets of Radial Plate Hardware.

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.

Tilt Base to Mounting Pipe

Install the patented Tilt Base to the 2" OD (maximum) mounting pipe using two DXE-SSVC-2P VBolt Saddle Clamps allowing approximately 7" clearance between the bottom of the Tilt Base plate, to the top of the DXE-RADP-3 Radial Plate as shown in Figure 3. Make sure the Tilt Base and optional DXE-RADP-3 Radial Plate are oriented correctly for the direction you wish to tilt the antenna. 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.

Figure 3

Vertical Base Section

The base section is made up of an insulated mounting channel with hardware, a mounting plate, two U-Bolt Saddle Clamp assemblies and the thick wall base antenna section which is 36" long, (with a hole drilled at bottom end having the feedpoint hardware pre-installed) and slits at the top end.

Using Figure 4, align the holes on the mounting plate and insulated channel. Attach the aluminum mount plate to the back of the insulated channel using four of the 2" bolts, four aluminum spacers, four flat washers, four split washers, and four nuts. Tighten firmly, but not enough to crush the insulated channel.

Figure 4

- 8 -

Locate the 36" base-section tube. This is the 2" OD, thick wall (1/8" thick) section that has a hole drilled for the feedpoint hardware. Install the feedpoint hardware as shown in Figure 5 using the 1" hex head bolt, two star washers, two flat washers and 2 hex head nuts.

Figure 5

Install the lower section to the insulated channel using the two 3/8" x 2" U-Bolts, two saddles, four flat washers, four split washers, and four nuts as shown in Figure 6. When tightening, observe the split washers. When they fully seat (flatten out), the clamp is tight enough. Any clamp should be tightened evenly from side-to-side with an equal amount of thread above each nut.

Figure 6

- 9 -

Base Section to Tilt Base

Place the Lower Base Section into the holes of the Tilt Base and loosely install the Tilt Base mounting hardware shown in Figure 7.

Figure 7

- 10 -

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.

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 Figure 8. 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. Gently pull up while raising, not pushing 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.

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 (reference Figure 7) is tightened.

Figure - 8 - Tilt Action

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 vertical when horizontal.

- 11 -

Assembling the Vertical Element Sections

Assemble the vertical element in an area that is flat and has sufficient room for the length of the antenna during assembly.

Note: JTL-12555 Jet-Lube™ SS-30 Anti-Oxidant should 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. Jet-Lube™ SS-30 should also be used on all element clamps and stainless steel threaded hardware to provide good electrical contact, prevent galling, allowing easier disassembly and to ensure proper tightening.

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. Our aluminum tubing is machine cut on

both ends and machine slit on one end. Although DX Engineering manufactured aluminum tubing is deburred, you should further assure that there are no ragged edges or protrusions.

Use the DXE-22166 Slim Grip Deburring Tool, or the DXE-22600 Deburring Tool with

Extending Handle and 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.

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. The use of JTL-12555 Jet-Lube SS-30 is highly recommended. Jet-Lube is an electrical joint compound which effects a substantial electrical connection between metal parts such as telescoping aluminum tubing or other antenna pieces. Using Jet-Lube assures high conductivity at all voltage levels by displacing moisture and preventing corrosion or oxidation.

- 12 -

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.

Using a felt tip pen, measure and mark the antenna element sections as shown in Figure 9.

Figure 9

Locate the 15 Element Clamps.

Refer to Figure 11 for clamp locations. Slide the clamps over the element sections before putting them together. Align the clamps on each element section facing the same direction. For final assembly, all the clamps should be positioned approximately 1/8" from the top of each element section and the body of the clamp should be positioned between the slits as shown in Figure 10.

Figure 10

Using Figure 11 on the next page, start the assembly with the bottom 2-1/8" element section. Insert the marked end of the 2" section into the 2-1/8" element section until the mark is even with the top of the 2" element section.

Position one of the DXE-ECL-2250 clamps at the very end, but not hanging over. Make sure the body of the clamp is positioned between the slits and tighten securely.

Repeat the procedure for the element sections using the Element Clamps as shown in Figure 11.

Mating the Vertical Element Sections to the Tilt Base

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 vertical when horizontal.

With the base section in the tilted position, mate the vertical element sections to the base element section by sliding the lower element section of the vertical antenna ove r the previously assembled base section element. Slide it until the bottom section (mounted in the Tilt Base) has 32” exposed (4 inch overlap). See Figure 11.

When the upper element sections are assembled together install the black vinyl cap in place at the top of the smallest element section.

Raising the Vertical

DANGER: Make sure you have not inadvertently l ocated the

antenna underneath power lines.

Residential power lines are often less than 40' high.

Contact With Any Power or Utility Lines Can Be Lethal !

The tilt-base certainly makes it easier however, this antenna can be challenging to put up the first time or with gusty winds. If you have properly laid out your optional guy system in advance, it will help keep the vertical stable as you raise it – and stop you from going beyond vertical at the apex of the lift.

Make sure the optional guy ropes are in the clear before you begin. While raising the antenna, keep a gentle pulling pressure away from the Tilt Base. This will ensure that the pivot point bolt will not jump out of the pivot slot and cause the tilt mechanism to bind up and bend the bolts.

Starting from the top of the antenna, walk it up slowly using an overhead hand-over-hand motion, maintaining a slow and steady pace.

The antenna mounting channel must be kept in parallel alignment with the tilt-base plate to prevent binding until it is positioned in the Tilt Base. Once the antenna is vertical, lift and slide the antenna toward the Tilt Base mounting pipe to allow the two parts of the Tilt Base to line up and drop down into the slots. Lightly tighten the top flange nuts on the Tilt Base to hold the antenna.

- 15 -

Note: As you raise the antenna to the vertical position, it’s important to

maintain the parallel alignment between the antenna mounting channel and the Tilt Base backing plate to minimize binding. Make sure the lower tilt-base bolts are never excessively loose before raising. They should be first tightened securely and then backed off no more than 1/2 turn

Once the antenna is fully raised, tighten the tilt base hardware (top two Nyloc nuts and two flange nuts, bottom two Nyloc nuts).

Feedline Connections

The most efficient way to make a reliable feedline connection using customer supplied coaxial cable is using the optional DXE-RADP-3 Radial Plate with the optional DXE-112-KIT SO-239 Chassis Mount Connector as shown in Figure 12.

Use a customer supplied insulated wire soldered on the center pin of the chassis mounted SO-239 (14 gage insulated wire is adequate - same wire used for DX Engineering Radial Wires) to a ring terminal which is connected to the antenna feedpoint hardware. Make the wire long enough so it will not bind when raising or lowering the antenna.

When connected in this manner, the customer supplied coaxial cable will feed the antenna and the shield will have a positive and reliable connection to the radial field.

Figure 12 - Feedline connection using the optional DXE-112-KIT SO-239 Chassis Mount

with the optional DXE-RADP-3 Radial Plate

To minimize stress on the feedline connection, make sure the feed point connection has sufficient slack when raising and lowering the vertical. Make sure all connections are tight.

Installing the DXE-VMN-1 Vertical Antenna Matching Network

The DXE-VMN-1 Vertical Antenna Matching Network is custom designed for use with base-fed quarter wave resonant vertical antenna systems. In some vertical antenna installations with excellent radial systems, achieving the best SWR on a resonant vertical for 60 meters may be difficult without some means of adjusting feedpoint impedance. The DXE-VMN-1 allows easy adjustment for lowest SWR.

As an added benefit the DXE-VMN-1 will also act as a static bleed for your vertical antenna in areas where precipitation static or snow static is present.

1. Use a small Phillips head screwdriver to loosen the tap clip screw and position the tap clip on the 6th or 7th turn on the coil as shown (this will be re-adjusted during tuning). Attach the Base Matching Network Assembly to the optional DXE-RADP-3 Radial Plate using the 1/4" flat washer, 1/4" split lock washer and 1/4-16 hex nut as shown in Figure 13. Verify the wires and coax will not be in the way when tilting the antenna.

Figure 13

Mounting the DXE-VMN-1 to the optional DEX-RADP-3 Radial Plate

- 17 -

Tuning the Vertical

It’s best to use an antenna analyzer for determining antenna resonance. Use the X=0 or +/- j0 readings to determine the resonant frequency. Later, the SWR will be adjusted by the impedance matching assembly mounted at the feed point once the vertical is resonant at the desired frequency. Do not use the DXE-VMN-1 for changing the resonant frequency, initially tune the antenna without the DXE-VMN-1 (remove the connection at the radial plate and isolate it. Do not let the “L” bracket touch the radial plate).

The 60VE-1P should resonate at approximately 5.368 MHz with the DXE-VMN-1 at the feed point, the recommended ground radial system installed and the vertical dimensions as shown in Figure 11. Resonance is adjusted by the length of the vertical sections.

If you are having trouble achieving resonance, make sure the tube section lengths are correct. Make sure you have at least 16 radials (32 are better), 30 feet long, symmetrically placed around the vertical. A very low SWR might indicate a poor ground radial system.

Connect the Tap Clip in the Base Matching Network at the 6th or 7th turn from the top as shown and proceed as follows:

Adjust the tap clip by moving the tap clip to a different coil turn on the DXE-VMN-1 Coil for minimum SWR on 60 meters. Disregard any frequency shift of the points of lowest SWR on this band at this time.

Recheck the lowest SWR. If the SWR is higher move the tap clip on the Base Matching Network Coil to a position that gives the lowest SWR on 60 meters. Securely tighten the tap clip when done.

At full length, the 60 meter vertical antenna should resonate at approximately 5.368 MHz with the VMN-1 impedance matching assembly at the feed point and the recommended ground radial system. Resonance is adjusted by the length of the vertical element sections.

The antenna resonant frequency may be centered at any point between these frequencies by merely adjusting the overall length. To raise the base resonant frequency, shorten the element tubing stack. Adjusting the vertical base measurement will move the resonant frequency 20 to 30 kHz. Measurements are taken from the bottom of the base element tube to the first vertical element section. To ensure sufficient nesting of the base tube, do not go beyond 29" of separation. The more of the base element tube that is nested, the stronger the bottom section will be. For maximum strength, the base section can be nested until it is slightly above the top clamp on the tilt-base. If a larger excursion is desired, the antenna should be lowered and the length adjustment made to the highest element section. As a rule of thumb, one foot of length should be approximately 50 kHz in frequency. A shorter antenna length = higher frequency and a longer antenna length = lower

frequency. Connect the Base Matching Network Assembly and adjust the inductance by changing the tap connection and watch for a change in SWR to obtain the best impedance match.

Once final tuning is complete and you have verified correct operation on-the-air, the DXE-VMN-1 coil tap should be soldered in place to eliminate any future intermittent connection due to environmental corrosion to the coil taps.

Guying a Vertical Antenna System

Guying of vertical antennas is always recommended for stability. However, if your area encounters severe wind velocities or icing conditions, simple guying will reduce the possibility of failure. Using the DXE-GUY kits, you can install four guy ropes starting approximately 1/2 the way up the vertical antenna system to ground level. Guying should be tightened just enough to permit the antenna to swing a few inches. The ends of the ropes are tied to the earth anchors that are screwed into the ground at about the same angle as the ropes will be. When using the Tilt Base, position the guy wires as shown below. This will make it easy to raise or lower the antenna and only one guy line needs to be loosened. The other guy lines will help guide the antenna on the way up. Depending on your antenna system, additional guys at higher points on the antenna may be required.

Jet-Lube™ SS-30 Pure Copper Anti-Seize is the top choice of engineers and technicians in government, industry and leading Amateur Radio contest stations, for protecting mechanical assemblies of aluminum tubing, general hardware and copper grounding systems. On bonded metal surfaces Jet-Lube™ SS-30 assures electrical and RF conductivity while preventing oxidation and corrosion. Surpassing the capabilities of other aluminum anti-oxidants, the wide temperature range of Jet-Lube™ SS30 prevents long-term drying and caking, and allows easy disassembly and effortless cleaning of parts. An environmentally preferred thread lubricant and conductive termination compound, Jet-Lube™ SS-30 helps keep your equipment in serviceable condition. It contains a high concentration of copper flakes, a requirement for heavy loads or compression; controlled frictional characteristics allow the surfaces of nuts and bolts to be tightened to their design torque specifications. This anti-seize product assures full hydraulic efficiency by allowing the metal surfaces to slide over each other without damaging metal-to-metal contact. Jet-Lube™ SS-30 is also designed to work as a similar and dissimilar component between two metal surfaces to prevent seizing and galvanic action. The SS-30 compound formula improves conductivity and ground continuity - and will not melt in high temperatures. Features include:

* Meets MIL-PRF-907E spec * K-factor: 0.13 * Service rating: -65 degrees F (-54 degrees C) to 1800 degrees F (820 degrees C) * SS-30 Resistivity (ohm-CM x 108) 5

DXE-RADW - 500K or 1000K Radial Wire Kits and Components

To achieve optimal performance with a ground-mounted vertical, install as many radials as possible. These bulk radial wire kits use insulated wire that is UV resistant, hard to see and lays down easily, unlike the wire that is commonly available at the big box stores. It will last much longer in contact with soil than bare wire. The DXE-RADW- 500K or 1000K kit provide everything you will need to build the perfect radial system!

• 500/1000 ft. spool of 14 AWG, stranded copper wire with vinyl insulation, 20/40 lugs, 100/200 radial wire anchor pins-

4 - Heavy Duty screw-in earth anchors with eyelets 1 - 1000 ft Roll - UV resistant, 3/32” Double-Braided Dacron Polyester Rope SYN-DBR-94-1000

Some vertical 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 reduce wind stress, regardless of direction. A four point guying system is recommended for use with a DX Engineering Tilt Base, 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. These 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.
