1.8 Lightning Protection
WARNING: The following notes are general recommendations for the system. The wireless
equipment should be installed by a qualified professional installer and must follow local and
national codes for electrical grounding and safety. Failure to meet safety requirements
and/or use of non-standard practices and procedures could result in personal injury and
damage to equipment. A direct lightning strike may cause serious damage even if these
guidelines are followed.
All outdoor wireless equipment is susceptible to lightning damage from a direct hit or induced
current from a near strike. Lightning protection and grounding practices in local and national
electrical codes serve to minimize equipment damage, service outages, and serious injury.
Reasons for lightning damage are summarized as:
- 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. The remaining energy on the RF cable shield and center
conductor can be directed safely to ground by using a lightning arrestor in series with the RF
cable.
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 arrestors 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.
