Been there, done that, many times. If the vertical is
a half wave, you can just use the shield of the coax
feeding it as the little bit of counterpoise you need.
In direct A/B comparisons to quarter wave verticals
over good ground screens, the no ground vertical
half wave is so close in performance you can't measure
the difference.

Coil loss is not an issue if you use the proper coil.

in a never ending quest to acquire antenna knowledge
i've been doing some reading of a paper back book
by a well know antenna guru who's now a sk.
he claims that if a vertical antenna is fed at it's base
with a parallel resonant l/c circuit and tapped on the
inductor to to get an appropriate swr match, it's
rf ground can be no more than a 3'x3' screen combined
with a rod in the ground.

in my mind, this seems to be something for nothing. if true
why do i read about the importance of having a number
of radials?

questions, comments, pronouncements from the gurus on high
most welcome. brickbats & complaints, etc 2&1 /dev/null
