Unfortunately nothing exists to stop the power of a lightning strike...only thing to do is unplug if you're home, put a surge supressor on your circuit box and above all have replacement cost coverage on your homeowner's policy.
Failsafe lightning protection??
I live in the foothills of the Blue Ridge mountains where we have some hellacious lightning storms. I would like to install my APS antenna and rotor up on a mast on the roof. My concern is of course a lightning strike blowing my tuner and whatever else in my system. What are the best lightning protecting devices for this? Thanks, Lee
