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