Hmmm. Maybe the LED warning signal logic can be applied to a remote
antenna switch to provide isolation from the antenna? The the above
sensing for near by static discharges, it can hold the antenna isolated
from the last discharge plus delta minutes before re-engaging the
antenna system for normal usage. Just a thought.

Yes, but to 'isolate' you need at least a coule of meters in my experience.
A coax relay won't do ...I have seen lightning flash over electrical wiring
in a room.

So maybe explosive charges that blow piece of the coax away.... ;-)

Dunno, I just get up, go outside, just above the door is the coupling piece in
coax, turn it lose, one end of the coax throw it in the garden, the other end
the same the other way.. that is what I do.
Takes 5 minutes.

If lightning then hits the antenna it follows the coax into the ground.
