This. Very little will protect you from a direct strike. Working for a WISP for a long time as a past life, I've seen radios physically split in half. Chunks of concrete taken out of walls near the equipment. Black ethernet ports that have functionally soldered themselves into the jack. Six

I would begin by referencing the grounding section here: https://www.blm.gov/sites/blm.gov/files/Lands_ROW_Motorola_R56_2005_manual.pdf Of utmost importance is that everything is bonded to the same potential. This means that if they have stuff on a roof, outdoor antennas or APs, whatever, it

hi, have seen and suffered from same. nearby strikes can cause enough surge to fry things. best solution - air-gaps where possible between devices (eg fibre to link switches), surge protectors on ethernet cables where needed (eg feeds from Access points) - and if the APs have external antennae

Are "surge protectors" really of much use against lightning? I suspect not, other than minor inductions tho perhaps some are specially designed for lightning. I wouldn't assume, I'd want to see the word "lightning" in the specs. I once had a lightning strike (at Harvard Chemistry), probably

I would try to isolate it with something like the RBFTC11 or similar if you can. They’re great boxes, but as with all things lightning you usually can’t protect from everything. I’ve had a lightning hit cause some major issues before at a tower site. You do what you can and keep suitable

Could you use a transceiver for the 1000Base-T? copper <-> fiber <-> copper that will create an ‘air gap’ on the data circuit. You still run the risk of a lightning strike entering through the transceiver power. You could filter that through a -48VDC power supply, rectifier/inverter pair.

+1 on the Ubiquiti surge protectors specifically designed for PoE gear in mind (other brands like Cambium that are outdoor AP or camera oriented may work equally as well). I would also recommend continuing to isolate and protect as much as possible. For example, connecting your outdoor PoE
