Communications, Services, and Additional Information

Outdoor Installations

You can mount this antenna outdoors. If you mount the antenna outdoors, you must provide the mounting hardware. For
outdoor installations, Follow the instructions printed on the back of the antenna.
Caution: An orientation arrow is printed on the back of the antenna that indicates the orientation for outdoor
installations. You must install the antenna with the orientation arrow pointing down to prevent any water intrusion
and to provide a drain for any moisture that may accumulate inside the antenna.
Suggested Cable
Cisco recommends a high-quality, low-loss cable for use with the antenna.
Note: Coaxial cable loses efficiency as the frequency increases, resulting in signal loss. The cable should be kept as short
as possible because cable length also determines the amount of signal loss (the longer the run, the greater the loss).
The antenna terminates with a RP-TNC plug after a short, 3 foot (0.91-m) cable. The mating connector to the antenna
is an appropriate RP-TNC 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. Silicon 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.
1. Use No. 10 AWG copper or No. 8 or larger copper-clad steel or bronze wire as a ground wire.
2. Secure the ground wire to a static discharge unit (lightning arrestor, Cisco Aironet AIR-ACC245LA-R or equivalent)
and then to a suitable building ground. If possible, route the ground wire from the discharge unit to the ground using
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 antenna cable enters the building.
4. Drill a hole in the building's wall as close as possible to the access point to which you will connect the antenna cable.
Caution: There may be wires in the wall. Ensure that your drilling location is clear of any obstructions 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. Connect the antenna cable to the access point.
