Not a simple , on size fits all answer
What happens depends on the frequency you are talking about ( I
assume 1.825 but if it is a multi band vertical ..then???) and how much
above the ground plane you are talking about
And the approximate foot print of your radial systems ( square lot
filled in with radials ?)
on 160M the raising of a few feet will likely have little affect if any
on the overall efficiency of the antenna if that was what you were hoping?

Hello Gang,
This is somewhat related to the "Will radials on ground help?" thread. I
have poked around in various discussion groups but haven't found a specific
answer.
Assuming I have a fairly decent radial system on the ground (60 radials of
various lengths, some longer than 1/4 wave, many shorter), what happens if
I elevate the feedpoint of a quarter-wave, base-fed vertical? Let's say I
have an aluminum mounting post properly bonded to the radial plate, the top
of which will serve as the "radial system" connection for the vertical. Is
there some fractional part of a wavelength that the feedpoint could be
raised and not lose the effectiveness of the on ground radial system?
Thanks, and HNY to all!

I was under the impression that If you have elevated radials and if you
take even one to the ground you might as well move all to the
ground..??Fred KB4QZH
