Lightning Arrestor
CCU 100 and Repeater 100 Installation Guide 11
Proprietary and Confidential
The recommended procedure for grounding the antenna system is as follows:
• Mount a copper ground bar near the antenna. This is the top ground bar.
• Mount a second copper ground bar near the CCU/Repeater. This is the bottom ground
bar.
• Connect the two ground bars with a #6 gauge green jacketed stranded wire or a #2
solid copper wire.
• Ground the antenna mount and the top coaxial ground kit to the top ground bar.
• Ground the bottom coaxial ground kit and the lightning arrestor to the bottom ground
bar.
• Connect the bottom ground bar to one or more earth ground rods.
• All ground wires should be connected straight to ground, with no right angle turns or
sharp bends in the wires.
• Install ground leads on coaxial grounding kits without loops or bends and install
grounding kits in the proper orientation per the manufacturer's specifications.
Lightning Arrestor
A lightning arrestor (or surge protector) capable of withstanding multiple lightning strikes
should be installed when using a remote mount antenna. This helps protect the
CCU/Repeater in the event of a lightning strike.
The lightning arrestor is fitted to the coaxial antenna cable at the SURGE end and the RF
jumper cable that connects to the CCU/Repeater module at the PROTECTED end. 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 #2AWG solid
or stranded wire. The ground wire must be crimped to this lug, never soldered.
Caution The lightning arrestor must be connected to an earth-ground.
