What would you define RF ground as? There seem to be a lot of different
ideas.


1. One needs to define properties or "regular" ground.

2. Illuminate it with RF of particular frequency and particular antenna.

3. Study the effect of 1 on 2 and you will get some idea. Amount of
reflection or absorption would be the indicator of how good "RF ground" it
is.

As far as suitability of "ground" to "work" with antennas it is somewhere
from horrible (rocky ground) to "perfect" (sea water, copper mine, etc.)

Other than that, if you can walk or swim on/in it and you expose it to RF,
then I suppose you could call it RF ground.
If there is no RF, the RF ground disappears :-)

Somethinglikethat?!?
