Shovel. Draw a line between them and start digging down. Dan Metcalf wrote: Yeah that’s what I'm thinking, basically my cat5 wire and POE system is the bond between the 2 separate grounds :-(...

Make sure everything is bonded together as 1 single grounding system.

Last night it took a hit, although it appears it came through the electrical and not the tower, but I’m not sure, the UPS was off, I reset it and it came back online --- but the POE injector did NOT, it was completely shot. Replaced the POE unit and the wireless gear came online, but started rebooting after about 15minutes (although it didn't this before, I just changed the POE from a 12v to 15v) tried a 24v POE, and the radio was still rebooting... Called the tower climber.. Anyways I looked over the ground and the tower appears to 3 ground rod off each tower leg and then the building has a separate ground rod - (unless its connected underground) Any thoughts?
