[Antennas] Installing Lightning Protection

Tue Jul 20 17:26:04 EDT 2010

I am installing lightning protection on my antenna system as I have set up my radio for remote operation and may not always be on hand to disconnect the antenna during a thunderstorm.
My antenna (an OCF Dipole) is fed by about 120 feet of coax cable which goes to the antenna via a buried schedule 40 pipe exiting from a below grade hole in the basement wall. I have bought Harger lightning protection which I intend to fit in a cabinet on the external wall just above where the transmission line enters the basement. I want to do this by fitting a T-piece to the schedule 40 just before the pipe enters the house. I would run the cable from the antenna up to the lightning arrestor and then back down again through the T-piece back into the pipe and into the basement.
The question I have is this: Will running the transmission line to the lightning arrestor and out of the lightning arrestor through the same pipe for about two feet from the cabinet to the T-piece where they separate and go in different directions compromise the level of lightning protection?
Thanks
