I disagree with u, Dick, on two points at least:
1. routing coax thru PVC, I have seen two problems with this, one is
water sitting in the pipe if it has any horiz. parts to it, and the
other,
bigger problem, is the possibility of the PVC catching on fire in the
event of lightning hitting and heating up that area. The PVC that I have
burned, burns brightly even after the heat source is gone--dangerous.
2. Placing the bulkhead inside the interior walls or on them ("between
the studs") means u are placing things that will catch fire very near a
hot spot if lightning wants to heat it. I would not take the chance.
When lightning hit my shack one time, it lit up several cables inthe
window
sill, and I had a five inch flame burning in my lower window frame!
I recommend passing the coax bulkhead fittings thru (mounting them in) an
insulating, fireproof panel. Disconnect all incoming wires to the rigs.
