Re: [TCML] Counterpoise Insulation from Ground



Hmmm.  RF grounding is one of those things that I don't have a firm grip on
in my mind, but if I might think out loud...

Intuitively it seems like a good ohmic connection to the Earth is important
and would indicate the relative quality of an RF ground system.  But
consider for a moment the use of a counterpoise, which has no ohmic
connection to Earth.  Once again, intuition suggests that a counterpoise
sitting directly upon a moist concrete floor might be a better ground than a
counterpoise two stories up in a wooden structure, but I really don't know
(nor do I know how to find out).  It could be that it doesn't really matter?
