Assuming that your apartment has 3 wire AC outlets, and that your 
power supply has a 3 wire plug, let that be the equipment ground.

Then sink the ground rod wherever the lightning arrester needs it to 
be.

As John said, if you have an RF problem, put a quarter wave 
counterpoise for the band where the problem is on the ground screw of 
the radio, or of the tuner if you are using an external tuner.

Subject: grounding question


I'm living in an apartment where they've agreed to let me put up an 
antenna on a
14ft pole but they only want me to have a single grounding point for 
my system.
I have a 9ft ground rod but I need both an rf ground to the radio 
itself and a
ground for my lightning arrester on the antenna.  Is there any way to 
ground
these both to a single ground rod?
