But it's not. We're on a 160' spheroid and constantly lost gear in
storms. The city had a crew come in and dig up a ring around the tower
and now there's 6 or 8 #0s. Nothing lost at that site since.

Yeah, I would think the tank itself is ground.

Common point grounding at the power ground would be the NEC answer.
I would do that for power grounds and surge suppressor grounds
because most surges come via the power lines.
For antenna mounting grounds etc, I would make sure they were in good
contact (bonded, perhaps with a separate bonding wire) to the tank or
railing or whatever metal structure you are attaching to.

*Subject:* [AFMUG] Grounding strategies for water tanks
We are going to be installing on several water tanks that do not have
any other carriers on them. I'm assuming there is probably not a
ground ring or system in place at these sites. The electrical
service is likely grounded independently using a ground rod at the pole.
These sites will have batteries and a charger at the bottom and
fiber/DC up the tower. Admittingly, I'm fairly (ok, very) stupid when
it comes to grounding systems. I understand that everything *should*
be bonded together. However, if the tank it's self doesn't have a
sufficient grounding system already in place, what is the best
strategy here?
Thanks,
Josh
