Random Wire - What Lightning Protection??

wrote:
Definitely NOT thousands..

My setup is shaping up like this...

100 ft random, far end feed, into a 10:1 balum located at the far end
attached to a ground rod, balum feeds into coax which is buried for
125ft to a ground block connected to a second ground rod then into the
house to a Realistic DX-160 receiver.
Am looking at installing the lightning protection at the far end.

Well, the "balun" will bleed off the static accumulating on the
antenna from wind, etc. But induced EMF will still be a problem.

I'd suggest getting a gas tube and putting it across the hi-Z (wire)
end of the "balun." The place for a "Zap Trapper" or equivalent would
be right behind the radio.

A better choice would be a supressor from Polyphaser (probably about
$70) or I.C.E. (probably about half that).

I.C.E. seems to move around a bit. Someone else should provide the
location since I haven't bought anything from them in a while and last
time I did, Google returned old and new locations.

As for a direct strike? Well, if you get one, without a full solution
-- probably about $400 -- you'll lose the radio, but this vastly
increases the odds of keeping the place to live!
