This happened last week.
This is what we use on the AC lines to protect our customer’s public safety equipment at their tower sites. They seem to work fairly well. This one did an excellent job of protecting the repeater by blowing apart and blowing itself out of the AC wall outlet. It was not taken apart, it blew apart! The repeater was unharmed. These are much cheaper to replace than repeaters.
The generator controller board, generator transfer switch and tower strobe/beacon controller did not fare so well.
For the antenna lines we use PolyPhaser units that are properly grounded.
Stay safe out there…
