Makes a great lightning rod so don't have it connected during a storm!

Thanks guys.
If the hangar has a metal roof....

For me, anyway, yes, though it was a TV antenna. Blew the coax clean out of the TV, backfed the outlet. TV obviously dead, two computers dead, clothes dryer dead. There was a cordless telephone on the same circuit as the TV, which allowed the current surge to kill all of the telephone devices in the house (this may be how it got the computers--both had modems), plus the telephone network interface outside. It's been 20+ years, so I'm sure there was stuff I don't remember, but yes, antennae are great lightning rods.

Disconnect the radio when you're not there. BNC connectors are super-easy.
