[Antennas] Ground rod questions (Ground currents)

[rbethman]

Loren,

You ARE correct!  However, a very poor power ground CAN have a definite 
impact upon upon RF systems and the noise they deal with.

That is the point I was trying to get across.  The neutral IS supposed 
to deal with imbalances.  The power system ground IS "supposed" to deal 
with short circuits.

BUT, sometimes the engineers that design the distribution system NEVER 
pay *any* attention to the soil conductivity.  Therein lies problems all 
over the place.

The power system ground at the pole which should provide a ground circuit to your power panel ground is not for RF short circuit to ground. Only short circuits in your power system.
