All outdoor wireless equipment is susceptible to surge damage from a direct hit or
current induced from a near strike. A direct lightning strike may cause serious damage
even if recommended guidelines are followed. Installing surge protection and following
grounding practices detailed in local and national electrical codes can minimize
equipment damage, service outages, and chance of serious injury.
The major reasons for surge damage can be summarized as:
Poorly grounded antenna sites
Improperly installed surge protection equipment
A lighting protection system provides a means by which the energy may enter earth
without passing through and causing damage to parts of a structure. A good grounding
system disperses most of the surge energy from a lightning strike away from the building
and equipment. Improperly grounded connections are a source of noise that can cause
malfunctions in sensitive equipment. The remaining energy on the Ethernet cable shield
and conductors can be directed safely to ground by installing a surge arrestor in series
with the cable. A surge protection system does not prevent lightning strikes, but protects
equipment by providing a low resistance path for the discharge of energy safely to
ground. If surge protection is required for the system, the following general industry
practices are provided as a guideline only:
The AC wall outlet ground for the indoor POE adapter should be connected to the
building grounding system.
Install a surge arrestor in series with the Ethernet cable at the point of entry to the
building. The grounding wire should be connected to the same termination point
used for the tower or mast.
Provide direct grounding connections from the RDL-3000 system, the mounting
bracket, and the antenna to the common building ground bus. Use the grounding
screws provided for terminating the ground wires.
