Installing the Antenna
Grounding the Antenna
Follow these steps to ground the antenna in accordance with national electrical code instructions.
Step 1
Use No. 10 AWG copper or No. 8 or larger copper-clad steel or bronze wire as ground wires for both
mast and lead-in. Securely clamp the wire to the bottom of the mast.
Step 2
Secure the lead-in wire to a static discharge unit (lightning arrestor, Cisco Aironet AIR-ACC245LA-R
or equivalent) and the mast ground wire to the building with stand-off insulators spaced from 4 ft (1.2
m) to 8 ft (2.4 m) apart.
Step 3
Mount the antenna discharge unit as close as possible to where the lead-in wire enters the building.
Step 4
Drill a hole in the building’s wall as close as possible to the equipment to which you will connect the
lead-in cable.
Caution
There may be wires in the wall. Make sure your drilling location is clear of any obstructions or other
hazards.
Step 5
Pull the cable through the hole and form a drip loop close to where it enters the building.
Step 6
Thoroughly waterproof the lead-in area.
Step 7
Connect the lead-in cable to the equipment.
