Mike, the problem comes from induced currents in the ground by the =
radiator.
That isn't affected by where the antenna is  fed but by to other things: =
the
polarization (horizontal or vertical) and the distance from the ground =
in
wavelengths.=20

Actually, an end fed half wave vertical is virtually identical in its
"ground independence" with a center fed half wave. The difference is =
that
the rig needs a good RF ground to keep it from floating up to the high =
RF
voltage found at the end feed point and so becoming "hot" with RF. But
whether or not there is a good ground doesn't effect the efficiency of =
the
system as an antenna much.=20

I'm sure you're right but I'm referring to a center fed vertical =
*dipole*
(ala Sigma GT5) and not an end fed vertical.
