Did you have a SPG? Was it tied to the service entrance ground? How about a
shack ground and the computers tied to that? Most likely is that strike
induced current in your house wiring and that found it's way to ground via your
We can't prevent lightning but we can take the measures to intercept that
energy, control it, and more important, direct it to ground (where it really
wants to go, in a bad way) before it enters our house.
As far at the tower and antenna, were the coax shields tied to the tower? What
kind of grounding system was the tower connected to? (The best is 75 ft of
ground radials for each leg with rods every 2X their height.) Was the mast
direct coupled to the tower before the rotator? If any of these items were not
there, then yes you'd stand to lose some stuff on the tower.
Sri abt that loss and glad no one was hurt nor any fire started in the house.
