    I installed one of these on the tower and exactly one week later we got hit. One of my competitors on the same tower was totally wiped out. Lost all his radios. I did not lose a single radio. All the surge suppressor modules inside this box were blown up completely so we had to use couplers to get the radios back on the air, but McCown sent out replacement modules overnight and we installed them a few days later. This unit saved us thousands. Good shit.
