Polyphaser has been a leader in lightning protection for over 45 years (that I know about) and probably has more commercial government
, and military communications
installs than all the rest of the other companies combined. I've serviced repeater sites where the antenna took a hit, blew it to bits and blew the Polyphaser off the common point copper plate, but the repeater still worked.
Now that doesn't always mean you are 100% safe from freaky lightning by using any lightning protection device. Nothing can give you 100% protection from lightning.
What I am saying here is you're much better off protecting your equipment
with Polyphaser units than not.
The reason I said "equipment" is because they make devices to protect landline coms including CO's and PBX systems, service
entrance points, EMP protection (nukes), etc. So they are not just a company that protects RF equipment
Look at it this way. They make a coax unit that will help protect your VHF radio
for about $60.00 (GSA price
, don't know what the street price
is). Seems a small price to pay for what is considered by many Coms professionals (including radio
AM/FM stations, military, cell sites, Amateur Radio Operators, etc.) as the go to device for protection.
BTW: I have never worked for them nor sold their equipment, but I wish I had a dollar bill for every one of their units I installed.

installs, the basic theory is applicable, especially coommon point grounding
of your Coms equipment. Page 79, et seq is a real eyeopener to the uninitiated!
