[AMRadio] Antenna Idea and lightning precautions

Motorola says the simple measure of placing a piece of pipe over the coax
where it enters the house and bending the coax sharply where it stops it's
downward run and enters the house is good. I KNOW that lightning goes in
straight lines and the few thousand amps on the coax would see the pipe as a
transformer with a single shorted turn that can handler thousands of amps
for long enough delay time for the juice to jump to ground . To help it
along. commercial installations strip the jacket off and wrap a copper strap
around the coax at the bend ( JUST BEFORE) AND CONTINUE ON DOWN WITH A
NUMBER 6 OR NUMBER 2 GROUND WIRE. The scrap of pipe, perhaps a foot long
need not be grounded it is merely a transformer turn that can " take it" a
very cheap insurance policy regardless of all the other really good advice
and opinion to be found on the sublect!  73 Mike
