There was a W3 maybe W3BC his last name was Wolfe or Wolf, maybe Ben Wolfe,
I used to hear him during the late afternoon about 4 P.M. when I was
sailing on the East Coast of USA, day after day working European stations
one after another. I was 300 miles out to sea, so I was closer to Europe
but he was working them easily, just like I could sitting out on salt water
with a full sized quarter wave vertical mounted on the top deck of a tanker.
I was intrigued, I called him, he was using a full sized vertical mounted
on the apex of his garage with three elevated resonant radials elevated 7
to 8 feet. He told me that elevated radials were far more efficient than
even the classic 120 broadcast standard radial pattern.
I later was told that in his younger days, Ben worked for FCC and was the
engineer responsible for that 120 radial standard.
The common denominator is coverage, 3 radials in the air provide a ground
return just like 120 radials buried in soil because there's no competition
8 feet up in the air.
I think if you could make the antenna you have into a loop you'd have a
much better antenna. Loops are ground system independent.
