By through do you mean from one end to the other as in a pass through, or
through the sides with connectors etc. I assume that the coax is just
threaded through the iron pipe and the piep is near to the ground with a
good grounding wire.
Never heard of that.
What if I just did that? That I think that I can do with some old waste
water pipe 2-3 in in diameter.
