Greets Adam And All,
Adam this sounds like a really good idea to me. Do others
have and comments on this setup. It seems to me that this
would really help to keep the house ground from floating
around. I have an outdoor Allanson on it's way now,
15kv-at-60ma. Quite a bit more power then the 9kv-at-30ma
I am currently running with so I know I need to do
more engineering.
Many Thanks,
Bill Parn
