2.7 Grounding & Lightning Protection
WARNING
! Indicates that serious damage to the equipment can result if the user does
not comply with the given instruction. A WARNING statement will describe the
potential hazard, its possible consequences, and the steps to perform to avoid serious
equipment damage.
Proper grounding of the outdoor equipment reduces electromagnetic interference,
provides lightning protection, and protects against electrical discharge. The source and
connection points for the building-to-earth ground in the vicinity of the antenna location
should be determined. A 5’ (1.5m) copper cable is provided with each radio for a ground
cable to allow the radio to be grounded to the applicable pole or to the mount in the event
a pole is not used for the installation. The pole or mount, as applicable, will need to be
connected to the building ground.
In addition to grounding the equipment, local building codes may require the DC
electrical cable to be protected from lightning strikes. In the event your local city or
county requires such a device you may use a Polyphaser circuit protector model # IS-
PSP-24, manufactured by Polyphaser Corporation (or equivalent model from another
manufacturer). The Polyphaser device is available from the following companies:
