Afternoon all. I am having to install 2 antenna masts --top of a building-- for the purpose of tracking bird migration. A 120v circuit will power the "control box" ,also on the roof, and I think 4 coax to each mast/antennas. i have a few questions here...
what size grounding conductor to masts?
two separate conductors OR one and hit both masts?
where would they originate from ? Trying to recall but i think there is only one "grounding plate" in the building and it is on the other end.
I appreciate any help on this. Thanks....

#10 AWG see 810.21.
I typically just run a #6 bare tapped of the closest point I can reach on the grounding electrode system.
