Subject: Topband: Grounding the ends of radials
I posted this on TowerTalk and I got a couple of responses as to why
the ends of ground radials should not be grounded.
Isn't it dependent on whether you want the radials resonant or not? And

OTOH connecting all the ends together with a wire that can handle the total
current would help balance the field..Yes or no?

I am guessing that Bob is talking about insulated wire on the ground. But
some specifics from him would be useful.
Frequently mentioned specific radial implementations, in no specific order:
1) Raised radials
2) Radials of insulated wire laying on ground or embedded in lawns, etc.
3) Bare wire
may be good but it ain't that good! :)

but if it was done with a ground rod that's not really much of a ground
for rf.
It isn't there to provide a ground. It is there to intercept return
rf, which flows not far below the surface. So a ground spike is a more
appropriate term. Ground rods are good for safety purposes.

possible! FWIW

Elevated radial wires perform much differently than buried radial wires.
Elevated, horizontal radial wires having self-resonant 1/4 wavelength used
as all, or part of an elevated counterpoise for a monopole, tee, or inverted
L should NOT have a low-Z (direct) path to the earth at the operating
I generally agree with you, Bob - especially with regard to not grounding
the far ends of 1/4 wave radials!! After all what we are trying to
establish is a low-impedance image plane for the vertical radiator to be
fed against! A 1/4 wave wire, grounded at the far end would have a high
arrays!
