Re: Counterpoise?

So, in this case my counterpoise would need to have about 50" across
(6x24" coil). I can get it out of strike range eaisly enough. 

As for the other purpose for the ground. I realize the danger in that, and
would like to address it somehow. Would a single small rod work? I'm
dealing with frozen ground here so I would like to minimize the problems.
I'll have the utility ground available, but I don't think connecting it to
the RF ground on my coil is a good way to make friends. :) I'll have it
connected to the neons and primary safty gaps. 

How about building the counterpoise and connecting it to a water pipe
somewhere? Would that be able to disipate the dangerous currents while
providing a decent RF counterpoise?
