I have an 80 ft metal tower that is cemented into a dirt ground. It houses two small antennas to send and receive signals for wifi. This tower's power source is not a home. It has a dedicated line that runs directly to its own power meter. This tower is about 300 ft from a concrete home. The Internet company says the tower itself is already grounded. I have other people who are saying it is extremely dangerous to not have it properly grounded with a copper rod. What are the potential dangers if lightening were to strike this tower? I live in Nicaragua where reliable knowledge is hard to find!! I would appreciate any insight!
