The pictures are worth studying. Grounding the antenna(s) when not in use is a good idea. Disconnecting the antenna from the amps may help, but if you go that route, best to disconnect all wiring, including ground. Any electrical path has the potential of providing a path for lightning.

I have a amplifier for 160m. 3 days ago a storm strikes my transmitting area, and two lightnings strikes one of the building wherein i have install my vertical antenna's support rope. This building has lightning protect. The result of these strikes was to cause damage to my amplifier. In particular all of the output mosfets destroyed. My ground system is a single copper ground rode, 1,5m length. Here you can see the antenna tuner: http://natural-gas.webs.com/antenna-tuner.JPG I am using for protect against antenna high voltage charges a 2.5mH r.f choke which is connected between antenna feedpoint and ground system. But after these results i suppose that it isn't works well. I am looking for an idea, or a cheap product to improve the lightnings charges protect for my equipment. Thank you in advance. _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
