This probably won't fully solve your problem, but I run a bunch of
Ubiquiti access points and similar -- I suffered a number of lightning
related outages, and then started using their TOUGHcable -

(don't forget to also get the special jacks / ends). Since changing to
this I've had no more issues. You should also look at

needed them, but...

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
