Quickie Vertical Antenna Base Support
A simple and easy field day or fixed support
by

There are many ways and methods to support a vertical antenna
There are many ways and methods to support a vertical antenna
either permanently
(fixed station operation) or for portable use, field day activities,
camping, etc.
This method I use is but one of them and
should give you some ideas to build on for your type of support situation
and your particular vertical antenna.
It is very simple to put together using
junk materials and your imagination!
The support in the picture below is for
portable or field day use and is made from 2 by 4's in an L shape of
which one side of the L is driven on and weighted down by your vehicle and
the other portion is used to mount the vertical antenna.
Notice that PVC pipe is used in the field day or portable version above.

All you have to do to set up for field
day is place the support on the ground, drive a wheel on it and stick the
antenna mast down inside the PVC pipe that is attached to the vertical
support. Very simple and quick! It is assumed that the PCV pipe has
already been properly sized for your antenna mast and mounted to the
upright support.
For a fixed station
support, you could use a 4 x 4 length of wood, PVC pipe, or other
non-conductive material suitable for supporting the weight of your
vertical.
Or, you could use steel pipe with a
length of PVC mounted along side it as an insulator from ground. There are
many ways to make this a fixed station support with a bit of ham
engineering.
Wire, plumber's tape, copper tubing, aluminum, chicken wire or other material can be used for building the radial ring with as many radials as you have room.
Remember to isolate the radiating portion
of the vertical from ground!
Alligator clips can be used to attach the radials to the ring, or they can be directly soldered, bolted, etc depending on the ring material you use.
