1. A system for controlling corrosion on a telecommunication structure, comprising:
a metal structure supported by a concrete foundation,
a telecommunication module, mounted on top of the metal structure and separated from the metal structure by an insulating barrier, configured to operate with 5G wireless standard,
a ground ring, oriented approximately around the concrete foundation and connected to the metal structure with at least three monopole grounding wires,
a grounding cable connecting the telecommunication module to the ground ring,
a base transfer station cabinet, offsite from the metal structure, including a plurality of cabinet ground conductor wires connecting to the ground ring, and
a hybrid cable, comprising a supply cable and a return cable, connects the base transfer station cabinet to the telecommunication module,
wherein the base transfer station cabinet provides supply current to the telecommunication module through the supply cable and receives return current from the telecommunication module through the return cable, and
wherein stray current from the telecommunication module is directed away from the metal structure by the insulating barrier, and the stray current is directed to the ground ring through the grounding cable.
