Put surge suppressors within 3' of the radio on the tower as well. Motorola recommended that forever and more recently UBNT started recommending that. On 10/25/2015 12:13 PM, Gino Villarini wrote: Yes On Sunday, October 25, 2015, Josh Luthman

Shielded cable to the SS for sure... Have you looked at doing fiber/DC up the tower and then distribute it out that way? Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373 On Sun, Oct 25, 2015 at 11:57 AM, Gino Villarini wrote:

Try shielded jumpers between the patch panel and wbmfg ss. Make sure everything grounds to the same point so you're not creating a ground loop. -Sean On Sunday, October 25, 2015, Gino Villarini wrote: > So we are loosing radios left and right due to lightning! > >
