From a thread on a different topic I viewed this picture
http://www.dutson.net/Ham/P6060006.jpg and it prompted
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.)
Thanks! & 73, doc kd4e
