Rick,
I noticed this response and have a question.
Background:
I have an 80m 4 Square insulated 25G verticals and another tower that is
grounded that I shunt feed for 160m. In all cases the radials are soldered to
a wire that goes around the concrete bases of the towers. Then there is a wire
or two from the ring to a plate that that has a female UHF connector on each of
the 4 Square towers or to a tower leg on the one that is shunt fed. Those
wires are probably 12-18 inches long and maybe #10 or so.
Question:
Based on your measurements, do you think I can make a noticeable improvement by
doing something different?
Thanks... Stan, K5GO
