I use Polyphasers throughout, but would never trust them to stop a direct lightning hit:

NOTHING will stop a direct hit.

I remember an incident in the 90's when lightning scored a direct hit on WGN Channel 9's antenna atop the Hancock building and knocked the station off the air for almost two and a half hours! :o

I would have loved to see that mess!  We lived across the street from the Hancock and about 1,000 feet below all the antennas!

I think I have found a resonable compromise. I can locate the shack to the other side
of the basement. Unfortunately that would be in the unfinished part and cetainly not as aesthetically pleasing, but limits my coax run to 140' instead of 250', and allows me to pick up the AC panel ground connected to the water inlet service pipe which runs back to the panel with .200"diameter solid copper wire. The panel is also grounded to earth by a rod that is hidden to me under a paver walkway.

I am going to ground my coax shield to another rod assumably 8' via the Polyphaser from the one I can't see(but have some idea where).

This should be tied into the AC panel earth as well from what I've read....correct?

Then to put a Leviton 51120-1 to breaker#1 in the service panel for whole house surge protection.

I also better put some rubber backed carpet squares and not stand barefoot on the concrete floor when operating. Serious voltage in those boat anchor finals  ::) ;D
