[BVARC] roof antenna lightning strikes

[John D'Agostino]

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
