It seems to me that the ground above my rock layer (@ 36-40”) gets really dry
during the summer. Does that dry dirt have enough conductivity to be useful?
I do not know the answer to that question.
Are there different answers depending on why we have the ground rod? (RF
ground, power line ground, or lightning protection)
