Grounding
your Semi-Tractor is important
Why: Most Semi Tractors are fiberglass or plastic of some form
and do not have a good grounding capabilities. Any
vertical antenna needs a good gound counter-poise in
order to work or work properly.
Where: You must drill a small hole in the frame of you Tractor
and make a very good mechanical connection. Fasten a
connector to the wire and fasten it to a screw and make
sure the screw is the right size for the hole and make
sure the connection is tight. Run the wire up in any way
you think is out of the way and is not going to be damaged
by the wind when driving and hook it to the Mobile
mount of your antenna.
Why More: You might get out much better, you will hear
better, and you might even eliminate some of
the ignition noise.
Can't get a match on your truc
mount??? Take another antenna bracket and
mount it right next to your existing bracket and
point it down to the ground. Screw in a
adjustable antenna such as a solar con or an
Astatic antenna with the adjustable rings.
Make sure the insulator is not on the antenna
when mounting it to the bracket. You want this
antenna grounded right directly to the bracket.
This will be your ground side of the antenna.
You can adjust your SWR with the tuning
rings and get your match right down.

Sometimes the big truck mirror brackets have
very poor grounding and this seems to be one
of the only ways to provide a good ground plane
so the antenna can work properly.
