Dave, I had high on two Beverages that were terminated right at the
fence line. I though I was doing the right thing by clamping in all the
fencing and posts. I was wrong. Only a few days ago I remove the fence
connections and repositioned the Beverage feed about 20 feet from the
actual fence with a single 4 foot ground rod. All I can say is wow!
the noise floor drop 4 S points but the BC reference signals did not
drop at all on either beverage. It was getting dark so I ran into the
ham shack and the first signal I heard was 9N7BC peaking 579. I know
this is not very normal engineering logic but all I can tell you is tat
the fence hookup turn a good antenna into a bad one. I have found that
small 30-60 foot pieces of insulated wires laid on the ground at the
feed or termination, at least, can't hurt. it is easy to do and the
experts can let flame me for making the suggestion, but stay away from
fences, barbed wire, and semi conductors believing they will enhance
your ground. IMHO they won't.
