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 figure
Another copper cable considered a "gold standard" for outdoor shielded +
9th ESD drain and ground wire, intended for long term rooftop and tower
installation is Shireen. There's a variety of types.

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,

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 just

You might look at mccowntech.com,
they make surge suppressors geared toward
the wireless provider market which are pretty good.
