Installation
Site Selection
Select a mounting location clear from power lines, structures and other antennas by a minimum of
your antenna height.
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.
Mounting Pipe
Use a thick-walled 1-3/4" OD galvanized steel mounting pipe
at least
4 feet
long. This will allow approximately 2 feet or more to be below ground and
about 2 feet above ground. A thick-walled steel pipe 1-3/4" 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 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.
