Remote Antenna Grounding

[bartletts]

Sorry if this has been addressed, but I can't find a response about grounding that matches my situation.

I have a remote wire antenna about 50 feet in the air. It is grounded to a ground rod at the base of the antenna pole which also acts as a counterpoise for the balun. It is not bonded to anything else.

I have about 90 feet of coax to my house. My radio is grounded to the house ground rod directly with a 6 ga wire a few feet outside my shack.

I cannot reasonably bond the remote antenna ground to the house ground and don't have them connected as I assume I could get potential voltage between the two independent grounds.

I am not sure what to do when I disconnect my antenna from my radio. I can shunt it to the house ground but that seems dangerous?

What do you do when your remote has its own ground and does not bond with the house ground - i.e. how do I handle the disconnected coax?

A ground rod is a poor counterpoise if any for an antenna. You might be better off with an actual counterpoise wire above ground and disconnect the ground rod at the antenna. In that case a lightning arrestor where the coax enters the house might meet NEC. Otherwise to meet NEC with your current setup you would have to bond the ground rod at the antenna to the main house ground rod with no less than 6ga copper wire.
