A lighting protection system provides a means by which the energy may enter earth without
passing through and damaging parts of a structure. A lightning protection system does not
prevent lightning from striking; it provides a means for controlling it and preventing damage by
providing a low resistance path for the discharge of energy to travel safely to ground. Improperly
grounded connections are also a source of noise that can cause sensitive equipment to
malfunction.
A good tower grounding system disperses most of the surge energy from a tower strike away
from the building and equipment.
To limit the equipment damage due to a lightning strike, the following practices are recommended
for the wireless system:
- Provide direct grounding from the antenna mounting bracket, the radio and antenna and the
lightning/surge protectors to the same ground point at the base of the tower or a ground bus on
the building. Use the grounding screws on the antenna bracket and the radio and antenna for
terminating the ground wires.
- The AC wall outlet ground must be connected to the same grounding system as the eNodeB.
