Check out Techpuppy’s post in the Lightning thread. He has a very interesting approach.
You might also look for lightning arresters. These devices connect to the wires and to the electrical service entrance ground. They are available for coax and other wire types. Some are quite sophisticated and expensive with gas discharge tubes, and some are cheap using spark gaps. I use the spark gap type. (Me……cheap?). They work for me.
To make $$$ when I was in HS, I installed rooftop TV antennas. Believe it or not, TV was rather new then and there was a good market. I always used lightning arresters that pierced the twin lead and made sure they and the masts were grounded. I never had a report of lightning damage from any of my customers.
