I had the experience of a direct hit to my antenna. It was a 130 foot cage
fed with ladderline. Coax was used the last 20 feet to bring it into the house. Inside I had a TS-440, a TS-820 and an MFJ 989C. The bolt destroyed the side of the antenna that went to the shield of the coax, the largest remaining piece was about 3" in length with most of it vaporized. The ladderline was vaporized, the other half of the dipole was untouched. The coax split open like a hotdog put in a microwave. The same stroke went into the electric utilities and blew every electronic device in the house except a cheap GE clock radio. A stroke went through the wiring in the ceiling and the explosive expansion of hot air blew all the vinyl siding off the front and one side of the house. The only fire damage was a small burn mark on the shack carpet where the coax laid on the floor. All antennas were grounded via the antenna switch and all ham gear was unplugged. All antennas had blitzbuggs and coiled coax before entering the house. These were tied to both RF ground and the single point electrical ground. What was strange was the stroke following paths along wood beams while ignoring good conducting copper wires 3 feet away. The only damage to the ham gear was a burn mark and heat distortion on the rear panel of the tuner. It's operation was unaffected. "chuck" wrote in message ink.net... Does anyone know of cases where houses have fried as a consequence of ham wire antennas, "protected" or otherwise? We all know of cases where electronics gets zapped but Jerry is concerned about his house. Be interesting to hear of actual cases, wouldn't it? Statistics would be even better, but I won't hold my breath.

Given the recent spate of serious thunderstorms, and the accompanying lightning, I'm a bit concerned about properly grouding the antenna so that I don't fry the house *smile*. I know about some articles on the ARRL site, but was wondering if anyone else had some ideas or pointers on how to practically do this ? Jerry |
