Cisco Aironet 5-GHz 13-dBi Directional Antenna (AIR-ANT5114P2M-N)
6. Adjust the position of the antenna to the desired azimuth and elevation angles and tighten all pivot hardware (4 places) to
a maximum torque of 55 in lbf (6.2 Nm). The bracket allows the antenna position to be adjustable to +/–45 degrees azimuth
and +/–60 degrees elevation.
NOTE : We recommend grounding the antenna. See Grounding the Antenna .
Antenna Cable Information
If the antenna is used with the Cisco 1552CU or 1552EU access point, the port A of the antenna must be connected to port 1
of the access point, port B of the antenna must be connected to port 3 of the access point, and port 2 of the access point must
be capped with the cap enclosed with the antenna.
Note: Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. Keep the cable as short as possible
because cable length also causes signal loss (the longer the run, the greater the loss).
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 foot (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, ensure 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
To ground the antenna in accordance with national electrical code instructions:
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.
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 foot (1.2 m) to 8 foot (2.4 m) apart.
3. Mount the antenna discharge unit as close as possible to where the lead-in wire enters the building.
4. Drill a hole in the building 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. Ensure that your drilling location is clear of obstruction or other hazards.
5. Pull the cable through the hole and form a drip loop close to where it enters the building.
6. Thoroughly waterproof the lead-in area.
7. Install a lightning arrestor.
8. Connect the lead-in cable to the equipment.
