Introduction

Congratulations on obtaining your DX Engineering Four Inch Super Duty+ Base Pivot Assembly
DXE-VA-Pivot-4. Now you can have a high-performance pivot base for a vertical antenna with a
four inch base section. This is the same super duty pivot base assembly used on the DXE-

7580FSVA-3 sixty-seven foot tall vertical antenna.

Features

High Strength Super Duty Plus Pivoting Fixture - US Patent No. 8,130,168

 Ultra-rugged construction for vertical antennas starting with 4 inch OD heavy wall tubing
 Massive Extren® channel insulator
 Laser-cut high strength Stainless Steel brackets
 All Stainless Steel Hardware

The optional DXE-VRW-1 Manual Winch for easy one-person raising and lowering of your
vertical antenna is available from DX Engineering. You can move the DXE-VRW-1 winch
between similar antennas in a multi-antenna installation.

This heavy duty pivot base system requires a heavy duty mounting pipe. Recommended installation
should provide up to 3" OD heavy wall galvanized steel pipe set in concrete. Schedule 80 pipe that
is called 2-1/2" has an outside diameter of 2.875" is recommended. 36" of the mounting pipe should
extend above ground level. Depth of the mounting hole and amount of concrete is dependent on
your antenna design, local soil type and antenna guying.

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. 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.

Tools Required

Two 9/16" wrenches, (one of them should be open-end)
One 7/16" open end wrench
One 1/2” wrench
Two 3/4" wrenches

Manual Updates and Information

Every effort is made to supply the latest manual revision with each product. Occasionally a manual
will be updated between the time your DX Engineering product is shipped and when you receive it.
Please check the DX Engineering web site (www.dxengineering.com) for the latest revision manual.

Please - Take the time to read the entire manual before you start assembly. There are plenty of

pictures and drawings to see, and if you read the entire manual first, you'll get a better feel for the
overall construction methods described. Assembly is not difficult, but there are a number of parts
that must go together in a certain sequence to make assembly easier.

Site Selection

Select a mounting location clear from power lines, structures and other antennas by a minimum of
78 feet (68 + 10 ft 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 80 feet).

Mounting Pipe

Use a customer supplied 2-1/2" schedule 80, which has an outside diameter (OD) of 2.895",
galvanized steel thick-walled mounting pipe at least 7-1/2 feet long. This will allow approximately
4-1/2 feet below ground and 37 inches above ground.

Some manufacturers use the term DOM (drawn over mandrel) which will give you a true OD
dimension. Other types of mounting pipe may be used but due to lateral strength needed ensure the
mounting pipe is strong enough. The material most available is ASTM A513 Type 5 which is a
1020 material. Some pipe suppliers list the material as either 1020 or 1026. Type 1020 has the
following properties:

ASTM A513 (1020): Up to 2-3/4" OD with maximum wall thickness of 0.25"
Tensile: 80,000 PSI. Yield: 70,000 PSI. Elongation in 2": 15%. Rockwell Hardness: B80
ASTM A513 (1020): Over 2-3/4" OD with wall thickness heavier than 0.25"
Tensile: 70,000 PSI. Yield: 60,000 PSI. Elongation in 2": 20%. Rockwell Hardness: B80

3.00" OD x 0.25" wall thickness (or more) of 65,000 PSI yield tubing may also be used.

- 2 -

Depending on your geographic location, various dealers should be able to supply the mounting post
you specify. The following dealers can supply DOM tubing: (Other dealers in your area may be a
better choice.)

Industrial Tube & Steel, Corp.: www.industrialtube.com

On Line Metal Store: www.onlinemetals.com

Speedy Metals: www.speedymetals.com

Note: DX Engineering does not recommend or endorse any specific vendor.

Metals Depot: www.metalsdepot.com

This mounting pipe must be permanently mounted in the
ground, preferably in a concrete base 2 feet by 2 feet by 4
feet deep (with gravel below for drainage). The antenna
system requires this type of mounting to help withstand the
lateral forces present on the antenna during wind
conditions and when operating the pivot function. Make the
hole deep enough to accommodate at least 4 feet of pipe
and 4 to 6 inches of gravel at the bottom for drainage. Set
the mounting pipe on the gravel, use the concrete to fill
around the pipe per the concrete instructions. 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
the mounting pipe is vertically straight.

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.

Coaxial Cable to Mounting Pipe

The coaxial cable should be routed to the base of the antenna system and be buried below the radial
system. PVC Conduit pipe may be used to house the coaxial cable. Bury the cable 6" to 12" below
ground level.

Radial System Suggestions

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, 32 radials, each 65 feet long, should be used with most low
band vertical antennas. DXE-RADW Radial Wire, a 14 gauge stranded copper
with a black relaxed PVC insulation wire is suggested for the best results.

The wire radials should placed as symmetrically as possible straight from the

- 3 -

feedpoint around the vertical antenna and spaced evenly, regardless of how many radials are used.

Note: UMI-81343 Never-Seez® or DXE-NSBT8 Anti-Seize should be used on all stainless

steel threaded hardware to prevent galling and to ensure proper tightening.

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 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. 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.

Note: The following assembly instructions are based on using a customer supplied

2.895" OD Mounting Pipe (referred to as 3” OD), with the optional DXE-
VRW-1 Manual Winch, optional DXE-RADP-3 Radial Plate with one
optional DXE-SSVC-3P V Clamp and the optional DXE-112 Chassis Mount
Coaxial Cable Fitting.

Radial Plate to Mounting Pipe

Place the optional DXE-RADP-3 Radial Plate over the 2.895" OD mounting pipe. Connections to
the antenna will be made via the optional DXE-363-SST bulkhead fitting SO-239 socket connector.
The DXE-RADP-3 Radial Plate comes with 20 sets of stainless steel hardware for mounting the
radial wires. It is suggested that 32 radial each 65 feet long be used, therefore additional DXE-

RADP-1HWK Radial Plate Wire Attachment Hardware Kits will be required.

Optional DXE-RADP-3 Radial Plate Mounted to a customer supplied 3" OD Mounting Pipe

Attaching Ground Radial Wires to the Optional 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 (DXE-RADP-1HWK) that contain 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 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.

Base Winch Mount Plate.

The winch can then be removed and stored. Do not leave the winch outdoors since extended

weather and sunlight may damage or weaken the strap. Refer to the section of the manual
“Mounting and using the Optional DXE-VRW-1 Manual Winch” for detailed information.

Suggested Feedline Connection

The easiest 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 F-1.

Use a customer supplied insulated wire soldered on the center pin of the chassis mounted SO-239
(14 gage insulated wire is adequate) to a ring terminal which is connected to the antenna feedpoint
hardware (See page 15). 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.
