There is no such thing as an 'RF Ground'.

Subject: [TowerTalk] Does prevailing grounding scheme promote large ground

 From everything I've read, the prevailing overall grounding technique is to
run a heavy duty copper wire from the grounding system around the tower,
back to the ground rod outside the shack wall as well as to run it to the
ground rod under where your AC power enters the house.

It just occurred to me that the AC ground wire, besides going into the house
and connecting to the chassis ground in the breaker box (where also all the
neutral white wires are connected) then proceeds throughout your house and
also to your ham radio shack equipment. It is here that the ground wire also
connects to all the chassis in your shack as well as the shields on your
coax connectors that also finds it way back outside your shack wall to the
ground rod; one huge ground loop.  I know that there are 2 issues here; RF
grounding and lightning protection. Any comments about that?

Thanks,

Dick, K0CAT
