Any idea how far apart is too far for the ground rods to be bonded? I've
got a new (well, old, new to me) antenna going up. It's a cushcraft R7
vertical, and is about 125' straight line from my service ground. I've
considered sinking a ground rod next to it and bonding the antenna to that,
as once I meander through the necessary path I'll probably have over 200'
of wire to make it. Not a big deal, but if I don't have to make that run
I'd rather not. It'll be connected to the main service ground via the coax
braid (lightning pro at house entrance), but I don't know if that's close
enough to have loop concerns.
