After 13 years of operating a WISP and trying different types of surge suppression I finally have standardized on NOT using surge suppression on POE equipment but rather making sure everything is bonded/grounded on tower properly. In all actuality i have barely lost anything over the last 3 years in fact haven't lost anything this year or last year and have more equipment in the air now than ever before.
Two years ago (2015) i had 2 towers got hit, don't know if it was direct or what but the 1 tower i lost a couple PMP-450 AP's (which ended up being repairable) and Ubiquiti M backhauls. The other tower i lost some PTP650 backhauls on. In both cases the towers ground was not bonded to the electrical ground which i have since fixed and not had a problem since. I think the best practice is making sure you are using shielded Ethernet cable and make sure the outer shield is grounded for static to escape. Also make sure the pole the radio is mounted to has a ground. I actually don't run ground wires up towers at all. I rely on the tower itself being the ground and the radio mounted to tower. Now this may be different in different parts of the country that might get more severe weather than Ohio but this is working for me. Sometimes I think all the POE surge suppression stuff is just for instances where you dont have stuff grounded properly, thats when it has a real effect of using that stuff.
