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.
