Yeah, that's what I did, and it worked very nicely. But it's also clear
that the ground at the AC entrance panel isn't doing so well itself. I've
got to find the relevant section of the NEC and figure out how I can
both comply with the code *and* put a ground there. I'm 100% sure that what
I did (5 foot copper pipes) for the radio ground isn't compliant for the
AC entrance ground.
