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.

Suggested Parts

DXE-RADP-3 - Radial Plate, Stainless Steel with 20 Sets of SS Radial Attachment Hardware

The patented DX Engineering Radial Plate is meant for those of you that have or are building a quarter wave vertical antenna and who want an easy, neat and effective way to connect those essential radial wires and the coax to your vertical antenna for the lowest takeoff angle and strongest signals. DX Engineering Radial Plate is laser

cut from tough stainless steel so that it has smooth edges, won’t corrode and will

always look good. You will be proud of how good your installation looks. This plate will work perfectly with most commercially available vertical antennas.

DXE-SSVC-2P - Stainless Steel V-Clamp for steel pipe, 2 inch V-bolt This V-Clamp is made in one size that fits Steel tubing or pipe from 1" to 2'' OD as used in antenna construction. The supplied V-bolt is long enough to attach tubing to thick plates and is made with anti-corrosive properties. The special Stainless Steel saddle has serrated teeth will clamp to the pipe securely by biting into the surface. For this reason, it is not recommended for softer aluminum tubing or pipe. Ideal for fastening a radial plate and antenna mounting to a steel pipe.

 Used to clamp 1 to 2'' (OD) steel tubing or pipe  Designed for attachments that don't require resistance to torque  V-bolt and saddle made from high-strength 18-8* stainless steel

*The use of an anti-seize compound is HIGHLY recommended to achieve proper torque and prevent galling.

DXE-RADW Radial Wire Kits and Components 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 relaxed 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 relaxed 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.

DXE-GUY-200 Guying Kit for Vertical Antennas Some vertical antenna manufacturers indicate their antennas do not need guying. During times of high winds or ice loading, some of these vertical antennas 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 the DX Engineering SAF-T-TILT™ Base, because just one of the guy ropes has to be loosened when you tilt the vertical antenna down. The remaining guys help stabilize the vertical antenna in three directions when being raised. For details on guying this antenna, refer to the Guying a Vertical Antenna System page.

See these and other options available from DX Engineering for this antenna system in this manual

refer to the Optional Accessory Items page.

Additional Material Needed but not Supplied:

 JTL-12555 Jet-Lube™ SS-30 Pure Copper Anti-Seize 12555 - To ensure good electrical

and RF connection for Aluminum Element Sections and also used on the threads of Stainless Steel Hardware to prevent galling (seizing) and aid in proper tightening.

 For a new installation: Antenna Mounting - Steel mounting pipe, up to 2.0″ OD, 0.25″

wall thickness, 4 feet long. 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 a new installation: Quick-Set or other type of Concrete - Mounting pipe installation

(type depends on your particular conditions and landscape).

Basics for All New Installations

Site Selection

Select a mounting location clear from power lines, structures and other antennas by a minimum of 55 feet. Consider overhead power lines, utility cables and wires. The vertical should be mounted away from local noise sources or other metallic objects which can re-radiate noise and affect the tuning, radiation pattern and SWR. Determine the direction you want the antenna to tilt down and make sure there is adequate clearance (at least 55 feet). There should also be a clear diameter of 70 to 130 feet from the antenna for the guying and radial systems that will extend away from the antenna.

Radial System

The use of a radial system is a key requirement for any high performance quarter wave vertical antenna system. With a vertical antenna system, the radials are the second half of the antenna. The radials contribute to the radiation efficiency of the entire vertical antenna system.

At a minimum, 20 radials, each 32 feet long, should be used with this antenna. Using 32 radials at 65 feet long is preferred and highly recommended. The extra radials help overcome unknown poorsoil conditions, improve bandwidth, and ensure the best performance possible from the vertical antenna. DXE-RADW Radial Wire, a 14 gauge stranded copper with black relaxed PVC insulation wire is suggested for the best results.

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 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 the 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 it will be virtually impossible to see them. An article describing this process is available on the DX Engineering website. Radials can also be buried just under the surface by using a power edger to make a slit in the soil.

Mounting Pipe

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 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, allow easier disassembly and to ensure proper tightening.

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 20 inches above ground. A thick-walled steel pipe 1-3/4" OD to 2" OD maximum is recommended 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 at least 2 feet of pipe and a couple inches of gravel at the bottom for drainage. Set the mounting 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 (depends on the type of quick concrete you purchase). Fill the hole until the concrete is level with the ground around it. Use a level on the mounting pipe as you fill the hole to be sure it is vertically straight. Allow to set overnight or per the concrete manufacturer’s recommendations. 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. A black vinyl cap (DXE-VC-2000, for 2” pipe) can be used to cap the top of the mounting pipe to prevent water and debris from getting into the pipe.

NOTE: When installing the MFJ-927 Remote Tuner option at the base of the antenna - the Mounting Pipe length above ground must be 24 inches to allow room for the remote tuner and mounting shelf. Refer to the DXE-MBV-ATU-1 manual for details.

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.

Assembly

Carefully un-box the antenna and separate the various parts. All of the element sections are 36" long. The 2-1/8" OD antenna element is slit on one end and drilled on the other end. All the other sections are slit on one end except for the top 3/8” OD element.

- 8 -

Note: The following assembly instructions are based on the MBVE-5A-4UPR

which includes the DXE-RADP-3 Radial Plate and the DXE-UN-43 UNUN, DXE-UN-BRKT Bracket with hardware using a customer supplied 2" OD Mounting Pipe.

Note: For reference purposes, an exploded drawing of the completed SAF-T-TILT™ base

is show in Figure 21.

Radial Plate to Mounting Pipe

Install the patented DXE-RADP-3 Radial Plate on the 2" OD customer supplied mounting pipe using the DXE-SSVC-2P V-Bolt Saddle Clamp as shown in Figure 1. 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. 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. Additional hardware kits are available from DX Engineering: DXE-RADP-1HWK contains 20 sets of Radial Plate Hardware. Check which direction you want the antenna to tilt. Mount the radial plate as shown in relation to the SAF-T-

TILT™ Tilt Base. For reference, Figure 19 shows a completed installation.

Attaching the optional 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, Nut) connect the optional ground radial wires to the DXE-RADP-3 Radial Plate as shown in Figure 2. Additional hardware kits are available from DX Engineering: DXE-RADP-1HWK contains 20 sets of Radial Plate Hardware.

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 relaxed 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 relaxed 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 65Ft lengths. See these and other options available listed at the end of this manual.

Depending on the number of radial wires used, space them out evenly around the Radial Plate like the spokes on a wheel. The Radial Plate will accommodate up to 60 radial wires (60 laser drilled holes), or up to 120 radials if doubled up.

Radial Wire Pattern

Figure 2 - Radial Wire Hardware Installation

Tilt Base to Mounting Pipe

Install the SAF-T-TILT™ Tilt Base to the 2" OD mounting pipe using the two 3/8” SSVC V-Bolt Saddle Clamps allowing approximately 3-1/2" clearance between the bottom of the tilt base plate, to the top of the DXE-RADP-3 Radial Plate as shown in Figure 3. (See note on page 8 if you are using the MFJ-927 Remote Tuner - the mounting pipe above ground must be longer and the tilt base moved upward). 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.

Aluminum Tubing Information

Caution

Aluminum tubing edges can be very sharp.

Take precautions to ensure you do not get accidentally cut.

Note: JTL-12555 Jet-Lube™ SS-30 Anti-Oxidant should be used between all antenna element

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.

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. DX Engineering aluminum tubing is

machine cut on both ends and machine slit on one end and you should further assure that there are no ragged edges or protrusions.

Use the DXE-UT-KIT-DBR 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™ SS-30 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™ SS-30 assures 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.

prevent galling, allowing easier disassembly and to ensure proper tightening.

Assembling the Vertical Sections

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 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, allow easier disassembly and to ensure proper tightening.

Assemble the vertical sections in an area that is flat and has sufficient room for the length of the antenna during assembly. Lay the tubing out in descending OD sizes. Orient the slits in the tubes toward the top of the antenna. The bottom 2.125" (2-1/8”) OD base section has slits on one end and the feedpoint connection hole at the bottom end. All the sections are 36" long.

Each tubing section is inserted 4" into the next larger tube. Assembly is easier if the overlaps in the tubing sections are pre-marked. A dark color felt-tip marker works well. Measure and mark 4" from the end of each tube without the slit using a marker so it will be clearly visible.

Locate the 14 Element Clamps.

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

Making sure dirt or grass does not adhere to the sections to be joined, insert the marked end of an element tube into the next sized element tube until the 4 inch mark on the element tube is even with the top of the larger element tube section. Position one of the element clamps at the very end, but not hanging over the edge. Make sure the body of the element clamp is positioned between the slits and tighten securely. Repeat the procedure with the marked end of the elements and the other element tubes using one of the element clamps as you work your way up the antenna length. Continue mating the smaller tubes inside the larger ones. Double-check the vertical sections you have just assembled. A black vinyl cap is included for the top of the antenna. Figure 9

Note: Refer to the DXE-MBVE-5A60MCK if you are installing the 60 Meter Conversion Kit - the upper element and black cap are replaced with parts included in the conversion kit.

sufficient.

2. Raise the base section up to move the upper bolt out of the safety channel.

3. Slightly tilt until the bolt slides off of the tilt base, which will;

4. Allow the bottom bolt to slide to the bottom of the lower safety channel. You can then lower

the antenna as needed. Remember to support the antenna when tilted down. Do not allow the antenna to rest on the ground without support. Doing so may bend the vertical antenna elements. The antenna will normally bend when raising or lowering, but this temporary bending will not be permanent.

While holding the base at approximately a 90 degree angle, slide the bottom 2-1/8” OD element section onto the black insulator, aligning up the two holes in the 2” OD aluminum tube with the two holes in the black insulator as shown in Figure 13.

Figure 13 - Mating the vertical antenna to the SAF-T-TILT™ Base assembly

Once the holes are aligned, install the stainless steel hex bolts with the flat washers, external tooth washers, split washers and nuts as shown in Figure 13.

Raising the Vertical

DANGER: Make sure you have not inadvertently located 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. See the Guying a Vertical Antenna System section of this manual for guy rope details. Make sure the optional guy ropes are in the clear before you begin. Under optimum conditions, this is usually a one-person operation.

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

Once you get the antenna near the SAF-T-TILT™ base,

lift and slide to the right (as shown) until the top bolt will,

drop into the SAF-T-TILT™ base slot. Once in place, tighten the upper and lower bolts to secure the antenna in place.

Figure 14 - Raising the SAF-T-TILT™ Base

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 to the right (as shown above) toward the tilt-base mounting pipe to allow top bolt to line up and drop down into the SAF-T-BASE™ slot. Once the antenna is fully raised, tighten the tilt base hardware.

When lowering the antenna, it is only necessary to loosen the upper and lower nuts 1/2 turn or so, eliminating the chance of dropping and loosing loose hardware on the ground, or trying to reach it when dropped beyond an arm-length away - un unsafe situation.

Assembling the DXE-UN-BRKT UNUN Mounting Bracket & UNUN

NOTE: If you are installing the optional DXE-MBV-ATU-1 Multi-Band Vertical Remote

Antenna Tuner Add-on Kit for 43 Foot Multi-band Vertical Antennas, you do not need to install the DXE-UN-43 UNUN. Please refer to Appendix 2 the DXE-MBV-

ATU-1 section of this manual for details.

NOTE: If you are installing the optional DXE-MBVE-5A60MCK 60 Meter Mono-Band

Conversion Kit - you will NOT be using an UNUN. You would use a COMTEK 1:1 Balun. Refer to the DXE-MBVE-5A60MCK Instruction Manual

(US Patent No. D597,086)

Using the #6 hex head bolts, #6 flat washers, and #6 Nyloc nuts, attach the DXE-UN-43 UNUN to the patented DXE-UN-BRKT UNUN Bracket with the SO-239 connector facing as shown below. Tighten the Nyloc Nuts so they are snug. Do not over tighten since the mounting tabs on the UNUN are plastic.

Attach the stainless steel studded element clamps to the UNUN Bracket using the Aluminum Spacers and #10 Nyloc nuts as shown in Figure 15. Snug the #10 Nyloc nuts just to the point that you can still rotate the custom studded element clamps. The Nyloc nuts will be tightened later.

Figure 15

Installation of UNUN Assembly to Antenna Lower Section

The completed UNUN and UNUN Mounting Bracket assembly are mounted to the antenna lower section. To allow easy installation of the UNUN Bracket to the lower base section, open the upper and lower custom studded element clamps as shown in Figure 16.

Figure 16

Position the UNUN and mounting bracket so the bottom element clamp is located between the feedpoint hardware and the black insulator shown in Figure 17. Tighten the element clamps to hold the assembly in place. Also tighten the Nyloc nuts that hold the studded element clamps to the UNUN bracket.

Figure 17

Feedline Connections

The DXE-UN-43 UNUN is attached to the feedline antenna connection using one 6” wire with ring terminals and one 7” wire with ring terminals. Connect the 6” wire with terminals from the antenna

feedpoint located on the antenna element to the terminal on the DXE-UN-43 UNUN closest to the

Red "+" on the label as shown in Figure 18. Do not over tighten the wing nuts. Hand tighten

them only, do not use pliers or other tools to over tighten the wing nuts.

Connect the other 7" wire with ring terminals from the terminal on the DXE-UN-43 UNUN closest to the Black "▬" on the label to the bolt on the angle plate as shown in Figure 18.

Figure 18

Your coaxial cable from the radio connects direct to the SO-239 connector on the DXE-UN-43 UNUN. Weatherproof this coaxial connection using TES-06132 - Scotch® Super 33+ and TES-

2155 - 3M Temflex™ 2155 Rubber Splicing Tape.

Tuning the Vertical Antenna System

The use of a customer supplied, high quality, wide range outboard tuner is required for any multiband trapless vertical antenna system. The tuner should be capable of tuning the wide range of impedances presented by the antenna and coaxial cable at all the operating frequencies. Tuners of this type generally have a good quality variable roller inductor and at least one large variable capacitor for fine tuning.

There are a number of outboard automatic antenna tuners available that are capable of tuning this type of high performance vertical antenna system.

Tuners which are built into transceivers lack sufficient impedance tuning range for this type of high performance vertical antenna system.

The actual impedance of the multi-band antenna is affected by local conditions, including proximity

- 23 -

to structures, other antennas, number of radials, or personal preference for the mounting location. It may be necessary to adjust the top element section slightly longer or shorter, or to vary the length of the coaxial cable, if tuning to best SWR is not achieved with your tuner on all bands.

The performance of this versatile, rugged antenna is highly dependent on the ability of your tuner to deliver a low SWR when tuned. Refer to your tuner user's manual for correct tuner operation.

Coaxial Cable and 160 Meter Notes

A 43 foot vertical antenna is a short antenna for 160, but it will get you on the air. In this instance, coaxial cable type is a very important item to consider. DX Engineering recommends a length of 150 feet of DXE-213U an RG-213/U to give most tuners the ability to match the antenna on the lower frequency bands where most tuning problems are encountered. One needs to examine the complex impedance (R ± j) to see the problem.

On 160 meters, the use of 150 feet of polyethylene dielectric cable (such as DXE-213U which has a Velocity Factor of approximately 0.66) will transform the 2 – j183 impedance at the output of the UNUN to a more tunable 38 + j180 at the tuner.

If you use 150 feet of coaxial cable that has a Velocity Factor of 0.85 (like foam dielectric LMR-

400), the impedance on 160 meters would be transformed to only 3.5 + j45 – still too low an R value for many tuners. In order to achieve the recommended results, the LMR-400 length would need to be approximately 190 feet.

In general - the higher the R value, the easier it will be for the tuner to match the antenna system to your transceiver.

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 one, two or three level guy ropes. Figure 20 shows a two level guying system. 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. The ropes are tied just above a band clamp at the height desired. 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.

Note: The DXE-MBV-ATU-1 Remote Automatic Antenna Tuner - MFJ-927- is limited to 200 Watts maximum power.

MFJ-927 Remote Automatic Tuner

Refer to the DXE-MBV-ATU-1 manual for details on assembly. The only changes when using the Multi-Band Vertical Remote Antenna Tuner on the MBVE-5A are:

1. Longer wire (with ring terminal) for the connection from the remote tuner to the MBVE- 5A feedpoint. This longer feedpoint connection (24-1/2”) is included with the MBVE-5A.

2. Positioning of the remote tuner shelf in relation to the MBVE-5A and the DXE-RADP-3 Radial Plate. Pictures shown below show how this is accomplished.

The DXE-MBV-ATU-1 Multi-Band Vertical Remote Antenna Tuner Add-on Kit for the DXEMBVA-5/5A Vertical Antennas is a remotely mounted automatic tuner system which also features proper feedline isolation for a 43 foot vertical antenna. The DXE-MBV-ATU-1 is the perfect

solution for the DX’er running modest power (200 watts maximum) who wants maximum

performance on any 43 foot tall multi-band vertical antenna.

Full performance on 80-10 meters with no mismatch coaxial cable loss! A no compromise system! A Bias Tee is included with this package for supplying the 12 Vdc power through the coaxial cable from your radio shack to the remote tuner.

Bias Tee and Operation

The MFJ-4117 Bias Tee (included with the MFJ-927 Tuner) is usually located inside the radio room and requires a +12 Vdc power source such as the DXE- PSW-12D1A AC adapter, 12VDC/1000ma. Follow the instructions provided by MFJ for both the Tuner and the Bias Tee. Once the power is applied to the tuner via the Bias Tee, your vertical antenna system is ready to operate on 80-10 meters.

NOTE:

Review the MFJ-927 Remote IntelliTuner™ manual for a detailed explanation of the MFJ-927 Remote IntelliTuner™ and the MFJ-4117 Bias Tee operation.

Installing the Bias-T incorrectly may cause damage to your radio.

There are 3 complete DXE-MBVE-5A antenna systems for use with either the MFJ-993BRT or MFJ-994BRT Remote Tuner.

There are two upgrade retrofit kits for existing DXE-MBVE-5/5A systems for use with either the MFJ-993BRT or MFJ-994BRT Remote Tuner. There is also one upgrade kit that has the hardware

needed to mount the MFJ-998RT Remote Tuner that the customer already has.

General Information

For new antenna installations (DXE-MBVE5AE-BRT/BRT3/BRT4), the antenna is installed as previously out lined in this manual. Additional clamps and hardware are included for mounting the MFJ Remote Tuner (MFJ-993BRT or MFJ-994BRT). The mounting method for either of these remote tuners is the same as outlined in this section of the manual.

For an upgrade to an existing DXE-MBVA-5/5A (as shown in the chart above), the parts in the upgrade kits are installed as outlined in this section of the manual.

The MFJ Remote Antenna Tuner Add-on Kit for the DXE-MBVA-5/5A 43 Foot Multi-band Vertical Antennas is a remotely mounted automatic tuner allowing operation up to 300 or 600 Watts depending on the model chosen. The MFJ-993BRT - 300 Watt or MFJ-994BRT - 600 Watt are the perfect solution for the DX’er who wants improved performance on the 43 foot tall multi-band vertical antenna. A Bias Tee is included with these special packages for supplying the +12 Vdc power through the coaxial cable from your radio shack to the remote tuner.

- 33 -

Installing the MFJ-993BRT or MFJ-994BRT option

1. Install the short ground wire in the corner hole on the tuner mounting flange using the 5/16”-18

Hex Nut, 5/16”-18 x 5/8” long Hex Head Cap Bolt, 5/16” Flat Washer, 5/16” External Tooth Washer, 5/16” Split Lock Washer and 3” Wire

Assembly. The other end of the short 3” tuner wire goes to the tuner ground wing nut connection on the tuner as shown.

2. Position one of the tuner mounting aluminum V-saddle

clamps 3/4” below the top of the thick wall tube as

shown. Refer to the photos on Page 36 for the positioning of the clamps in as compared to the antenna base.

Use two 5/16”-18 Hex Nuts, two 5/16” Flat Washers, two

5/16” Split Lock Washers and one 5/16”-18 x 4” long UBolt. Do not over tighten the U-Bolt Hex Nuts which can break or bend the aluminum V-saddle clamp. Evenly tighten each side of the U-bolt until the split lock washer is seated properly.

3. Loosely mount the bottom aluminum saddle clamp assembly approximately 13-1/4” below the previously (upper) mounted saddle clamp using the same hardware described for the upper clamp. Ensure both clamps are facing the same direction.

(This installation method works well since the

MFJ tuner mounting flanges can be in slightly different positions on the tuners.)

- 34 -

4. Place on 5/16” External Tooth Washer on each leg of the upper saddle clamp U-bolt and then

position the MFJ-993BRT or MFJ-994BRT tuner in place on the upper U-bolt that protrudes from the saddle clamp. Once in place, loosely install the two 5/16” Flat Washers, two 5/16” Split Lock Washers and two 5/16”-18 Hex Nuts to hold the tuner in place on the upper clamp as shown. You want the tuner to be able to move a bit for final positioning.

5. Position the lower saddle clamp (with the external tooth washers on each leg) so the U-bolt will pass through the bottom mounting flange on the tuner as shown. Once the tuner is positioned in place and straight - use the two 5/16” Flat Washers, two 5/16” Split Lock Washers and two 5/16”18 Hex Nuts to hold the bottom of the tuner in place. Tighten all of the tuner mounting hardware (top and bottom).

6. When the upper antenna parts are mounted to the base assembly (see previous installation instructions), install the Studded Band Clamp on the first element just above the black insulator with the stud facing the side nearest the tuner connections. Install the 10” long tuner wire on the

studded band clamp using the #10 hardware as shown. The other end of the 10” wire is

connected to the tuner output wing nut connection on the tuner as shown.

- 35 -

A coaxial cable jumper between the Tuner input and the Radial Plate ensures proper connection of the radial field to the antenna system. The feedline coaxial cable going from the radial plate to the Bias-T in the radio room connects to the other side of the connector on the Radial Plate. See the Bias Tee Information - Appendix E and Appendix F- Coaxial Cable Connection to the optional

DXE-RADP-3 Radial Plate.

1. Install the four 1/4”-20 x 3/4” long Hex Head Cap Bolts, four 1/4” External Tooth Washers and four 1/4”-20 Hex Nuts on the tuner shelf bracket as shown. The hex bolt heads will be on the same side as the logo on the tuner shelf bracket.

2. Loosely install the two 4” long U-bolts, two V-saddle clamps with the 5/16”-20 Hex Nuts, 5/16” Flat Washers, 5/16” Split Lock Washers and 5/16” External Tooth Washers as shown on the tuner shelf bracket.

3. With the U-bolts loose, you can slip the assembly onto the lower base tube. <Hint: If you tilt the base, it

makes it easy to do this part of the installation.>. Position the top U-

bolt 4-1/2” below the top of the base tube as shown. (Refer to Page 40 for photos showing the positioning of the clamps and tuner). Once positioned correctly, tighten all of the hardware holding the tuner shelf assembly to the lower base tube. Do not over tighten the U-Bolt Hex Nuts which can break or bend the aluminum saddle clamp. Evenly tighten each side of the U-bolt until the split lock washer is seated properly.

4. Place one 5/16” External Star Washer on each of the four bolts that are installed in the tuner shelf bracket and then place the MFJ-998RT Tuner on the bolts as shown. Position the tuner so it is straight and the large hole on the tuner metal bracket is close to the antenna (this is where the feedline wire will pass through). Use one 1/4”-20 Acorn Nut on each of the bolts to secure the MFJ-998RT tuner in place.

5. When the upper antenna parts are mounted to the base assembly (see previous installation instructions), install the Studded Band Clamp on the first element just above the black insulator with the stud facing the side nearest the tuner connections. Install the 10” long tuner wire from the studded band clamp using the #10 hardware. The other end of the 10” wire is connected to the tuner output wing nut connection as shown.

Appendix E - Bias Tee Information

The MFJ-4117 Bias Tee is included with the MFJ Remote Tuner. Since the coaxial cable is supplying the DC voltage to the remote tuner (injected in the coaxial cable by the Bias Tee), the coaxial cable used must have a good DC path. Lightning protectors that block DC cannot be used.

Follow the instructions provided by MFJ for both the Tuner and the Bias Tee.

Make certain the coaxial cables are properly connected to the Bias "T" as shown. Ensure the ON/OFF switch on the Bias "T" is turned ON when using the system.

NOTE: Review the MFJ Remote IntelliTuner™ manual for a detailed

explanation of the Remote IntelliTuner™ and the Bias Tee operation.

Installing the Bias Tee incorrectly may cause damage to your radio.

DXE-RADW-1000K

Bulk Radial Wire Kit, 1000 ft Spool of Wire, 40 Lugs, 200 Staples

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. The guying kits are ideal for fixed or portable installations.
