Greetings All,
It seems this discussion has morphed into a discussion on ground planes for
regular vertical antennas where if I read the authors description correctly he
is using a Hi-Z amplifier. This may mean a whole different ground system would
be very satisfactory. I believe it was
Thanks for providing that link 8 years ago. Around that time I was
working on a talk about antennas and radial/counterpoise systems for
160M that I subsequently gave at Pacificon, Visalia, and to several
local clubs. Almost othing in the talk is my original work, but rather
collected great
As many of you may know, this Friday (May 8th) is the 75th Anniversary of VE
Day . . .
So to commemorate the ending of WW2 in Europe, I shall be operating the
special station GB4VE.
(both my late parents served in the Royal Navy during WW2, so I thought this
would be a nice tribute)
I shall

Thanks for the link, Craig. While I agree with the author's premise
that the ground screen provides capacitive coupling to the earth, I
do NOT agree that the capacitive connection is what makes the
antenna
Another thought.
Changing to a good ground system with a good choke at the antenna
feedpoint will make your vertical omnidirectional, but that may not
solve the noise problem,. You may need a directional receiving antenna
to reduce it.

Without more detail of your system, the cause is only a guess. Here are
some possibilities.
A single wire isn't much of a ground plane. It will make a vertical
directional. When you change from a single wire to a different ground
system you will change the antenna pattern. You should
