- Poorly grounded tower/antenna sites that can conduct high lightning strike energy into equipment.
- Lack of properly installed lightning protection equipment that can cause equipment failures from
lightning induced currents.
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.
Outdoor Ethernet Cabling
- Ethernet cable connected to should be outdoor grade with UV protection.
- Use shielded out CAT5e (minimum) cabled terminated with metallic RJ45 connectors.
- In order to protect any indoor units, install surge protection circuits on all copper cables on their
entrance to the building.
- Surge protection circuit must use a minimum 16AWG grounding cable.
