Introduction
The DX Engineering DXE-MBVE-5A series of antennas are designed from the ground up to offer
ease of use, reliability and performance. The design was based on older 43 foot verticals enhanced
with the newer tilt base, the overall length has been shortened from 43 feet for optimum
performance. A fast taper multi-band vertical antenna system with the patented SAF-T-TILT™
base (US Patent Nos. 654,064 and 8,686,919). The massive 3/8” thick rugged aluminum base
allows easy, safe tilt action without unsafe removal of mounting hardware. The vertical antenna
operates from 160 meters through 10 meters using a good quality outboard customer supplied tuner.
There are also options available for remote tuners allowing operation at 200, 300, 600 or 1500 Watt
power levels. There are no traps, coils or linear loading elements. Designed with 6063 corrosion-
resistant aluminum tubing and stainless steel hardware, this antenna is very durable and attractive.

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.
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. A standard 1-1/2" galvanized water pipe (with its 1.9" OD) will work for this
application and can usually be found at your local home building supply store. DX
Engineering also has the DXE-VGMT-2CG Steel tubing for ground mount antennas made
from high strength Chromoly: 2 inch OD x .25 wall thickness x 5 foot 4 inch length.
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 poor-
soil 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.

- 8 -
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 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. A steel mounting pipe, up to 2.0" OD,
0.25" wall thickness. A standard 1-1/2" galvanized water pipe (with
its 1.9" OD) will work for this application and can usually be found at
your local home building supply store. DX Engineering also has the
DXE-VGMT-2CG Steel tubing for ground mount antennas made
from high strength Chromoly: 2 inch OD x .25 wall thickness x 5 foot
4 inch length. 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: 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.
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 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 must 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 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. A steel mounting pipe, up to
2.0" OD, 0.25" wall thickness. A standard 1-1/2" galvanized water pipe (with its 1.9" OD) will
work for this application and can usually be found at your local home building supply store. DX
Engineering also has the DXE-VGMT-2CG Steel tubing for ground mount antennas made from
high strength Chromoly: 2 inch OD x .25 wall thickness x 5 foot 4 inch length. 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.

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.

Aluminum Tubing Information
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 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 must 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. 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.

- 15 -
Assembling the Vertical Sections
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 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 must 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.
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.

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.

Mating the Vertical Sections to the SAF-T-TILT™ Base
Note: Sawhorses or ladders should be used to support the vertical sections during assembly
with the SAF-T-TILT™ Base and whenever the vertical is tilted down. As shown in
Figure 12.
When the upper element sections are assembled together install the black vinyl cap in place at the
top of the smallest element section.
Figure 11 - SAF-T-TILT™ Tilt Action
1. Loosen the two large bolts just enough to allow movement. 1/2 turn or so should be
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.
