Back in the radio dark ages of the late 1960s, I had a tri-band beam
about 12' up from the peak of my roof. When not in use, I would
disconnect it and put a small SO239 coax pigtail with a neon bulb
soldered across it. You could see the effects of lightning all across
the Chesapeake Bay by watching the neon bulb flash.

Just as an fyi. Even if a storm is not nearby I have noticed on HF
brief power surges on my display screen that shoots across the band
meter making a crackling noise which I have been told is lightning….

You don't have to receive a direct hit to have issues.
Last year, I had an Armstrong Dipole made of two 80 meter hamsticks
20 feet up on 4 inch PVC drain pipe right next to the house. My ham
equipment was turned off and I was using the computer instead,
sitting at the same position. There was a lightning strike close by
but not directly. Just as I saw the flash outside I heard a
loud snap in my station monitor. After the storm I tested my
equipment and it was working well. A few days later my transmit /
receive relay became intermittant in the receive position, which
required cleaning of the relay contacts.
I believe that what I experienced was an "induced" Voltage and not
any kind of direct hit. I now disconnect the antenna cable if not in
use.

Subject: [BVARC] roof antenna lightning strikes
How common are home roof antenna (12 foot or less) lightning
strikes in
Houston?
How many BVARC folks have had a lightning strike on their radio
(or TV)
antenna (elevation 12 foot or less) on their roof?
Is this a Stir-Crazy Net subject?
Thanks,
Mike
