Lightning Arrestor
Install a lightning arrestor (or surge protector) capable of withstanding multiple lightning strikes
when you are using a remote/external antenna. This helps protect the collector or repeater in the
event of a lightning strike.
The lightning arrestor is fitted between the coaxial antenna cable and the RF jumper cable that
connects to the collector or repeater module. It includes a bulkhead connector interface that
mounts to a ground plate with a washer and nut. The arrestor is also furnished with a ground lug,
if your installation does not have provisions for a ground plate. The ground lug on the arrestor is
designed for #2 AWG solid or stranded wire.
Caution: The lightning arrestor must be connected to an earth-ground.
The ground lug is manufactured by AMP/Tyco Electronics (part number 320754) and is
designed for #2 AWG solid or stranded wire (0.257-inch to 0.335-inch diameter). The lug must
be properly crimped (never soldered) to the wire using SOLISTRAND tooling designed for the
lug. The following figure details a proper crimp.
