Cisco Aironet 5-GHz 14-dBi Directional Antenna (AIR-ANT5114P2M-N)
78-20958-01
Installing the Antenna
Note
The antenna cable has a 0.5 in. (12.7 mm) bend radius. Sharply bending or crimping the cable may cause
a degradation in performance.
The antenna terminates with an N-male plug after a short, 2.5-ft (0.76-m) cable. The mating connector
to the antenna is an appropriate N-female jack. The connector on the opposite end will vary according
to the type of equipment used.
After the cable is attached to the antenna, make sure that the connections are sealed (if outdoors) to
prevent moisture and other weathering elements from affecting performance. Cisco recommends using
a coax seal (such as CoaxSeal) for outdoor connections. Silicone sealant or electrical tape are
not
recommended for sealing outdoor connections.
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 an antenna discharge unit 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
Install a lightning arrestor.
Step 8
Connect the lead-in cable to the equipment.
