If what you've done isn't working, then it isn't enough, not that it's too much.

If there was no fuse, I bet the SS would continue clamping and start smoking if there's enough current to supply it. I don't know if it helps save things, but I'm leaning towards yes. Just getting all of the radios on the same DC bus seems to have helped quite a bit as well.

Very rare, but always during storms. It is possible this is saving radios, I can't say for sure. -----Original Message----- From: George Skorup Sent: Sunday, October 25, 2015 12:34 PM To: af@afmug.com Subject: Re: [AFMUG] Site Grounding - what we are doing wrong? One thing we've been doing for several years now is a bonding wire up the tower. I do not trust the tower steel/leg joints being low enough resistance. Failure rate went way down. DC and fuses doesn't hurt either. On 10/25/2015 10:57 AM, Gino Villarini wrote: <blockquote> So we are loosing radios left and right due to lightning!
