AV-6160 43-Foot Vertical Antenna Instructions revJ
5
Step-By-Step Procedure
Note: Select a mounting location clear of power lines, structures and other antennas. Consider
the proximity of overhead power lines, utility cables and wires . The vertical should be
mounted away from local noise sources or metallic objects which can re-radiate noise and affect
the radiation pattern.
Note:
The use of radials is required with any vertical antenna for optimum performance. If
possible, a minimum of 16 radials should be used and the radials should be at least 43 feet long
(the length of the antenna). However, more short radials are better than fewer longer radials.
Increasing the number and length of the radials will improve performance. Radials should be
connected as close to the base of the antenna as possible. A good location for connecting radials
is the U-bolt mounting nuts on the ATB-65 base mounting assembly.
Mounting Pipe Installation:
The mounting pipe should consist of a 4-foot length of thick-walled (1/8” minimum) galvanized
steel pipe with an outside diameter of 2”. Do
NOT use aluminum, as aluminum will corrode in
short order. Dig a 1-foot diameter hole deep enough to accommodate 2.5-feet of pipe and a few
inches of gravel at the bottom for drainage. 18” of pipe should extend above ground level.
These are minimum requirements in that a longer pipe, deeper mounting hole, and larger
diameter hole is better – especially if your ground soil is somewhat unstable (moves due to
freezing/thawing or moisture content). Set the pipe on the gravel and pour concrete around the
pipe until the concrete is level with the ground. Use a level to ensure that the pipe is straight.
Allow 8-10 hours for the concrete to set.
Alternative Mounting Pipe Installation
You may elect to support the antenna by bracketing it to your house, wood fence or other
structure. If you elect to do this, it is not necessary to pour concrete for the mounting pipe.
To bracket the antenna to a house, wood fence or other structure, place a piece of 2” PVC pipe
around the antenna and use a 2” galvanized fence post support bracket to affix the antenna to the
support structure. The fence post support bracket should go around the 2” PVC pipe as shown in
Figure 1 below. Add one or more 2x4” treated wood spacers as desired to space the antenna
away from the supporting structure as shown in Figure 1.
