Doc:
More food for thought: check out Bill N3RR's web pages on his tower
installation, in particular the pages on lightning protection:
http://users.erols.com/n3rr/lightningprotection/index.htm . I learned a lot
from these pages and from visiting his QTH a few miles from here.

Subject: [TowerTalk] Entry Panel in Wall or External to Building?
> From a thread on a different topic I viewed this picture

> a question.
>
> It is best to mount the Polyphaser/ICE/whatever lightning
> protection panel in the wall or window of the building
> or in a panel/box that stands apart from the building?
>
> I have been planning a box on a steel post a few feet from
> the outer wall and to then feed the cables through a length
> of 4" pvc into the radio room.
>
> What is the greater risk?
>
> 1. The discharge through the multiple Polyphasers to
> ground when mounted in the wall or window bringing a
> heavy charge into the shell of the building? (Note:
> in my case the building is steel.)
>
> 2. Energy reentering the cables between a freestanding
> grounding panel between it and the house? (Note: Does
> the fact that my building is steel represent a mitigating
> factor, tending to siphon-off energy to ground.)
