So, was the tower mounted equipment isolated with its own ground wire?
Curious about the improper isolation at the entry point.
What was the proper way and what did the improper installation do to violate
that?

I’ve only ever encountered one tower (at former job) that was pretty
“bulletproof” …
The tower was 350ft and located on the highest elevation for about 100 square
KM area … so it was a prime target for lightning strikes. I don’t know exactly
how many times a year it took a hit but would guess at 8-10 times per year it
would have a direct hit. There was only one time where any damage occurred and
it was because of some shoddy updates by a 3rd party contractor whom didn’t do
proper isolation at an entry point (effectively bypassing some layers of
protection).
That site had a full cellular deployment along with several PTP600’s for
backhaul and PMP320/PMP100 - with the cellular being at the very top and the
Cambium gear further down.

No such thing as a bullet proof tower. At least not in my area. All the
over-engineering in the world can't stop a direct strike. Some days you get
lucky, some days not. It's a roll of the dice.

I am asking for pure simple curiosity.
How far would you go and how much would you spend to have a bullet proof
Tower site?
I am looking for answers in small class tower to super duty types or leases.
What I mean by bullet proof is How many time a year are you replacing gear
due to weather complications
or how many times are you going to back to the site to reboot something .
How many times are you remoting into a
site to adj power or channels to avoid interference. How many times are you
having to make adjustments to ethernet ports.
All these tasks add up in time.
Our team this year has only had to visit 2 sites unexpectedly due to
weather and take the next step in making it bullet proof.
