Step 4
Slide the antenna and base brackets onto the U-bolt threads.
Step 5
Secure the antenna to the U-bolt using two 5/16 x 18 hex nuts and two 5/16-in. lock washers.
Step 6
Tighten the hex head bolts evenly using a 1/2-in. wrench or adjustable wrench.
Step 7
Remove the yellow mounting instruction label.
Step 8
Route the antenna cable to the wireless device.
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-ft (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, 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. Silicon sealant or electrical tape are
not
recommended for sealing outdoor connections.
Grounding the Antenna
The antenna should be grounded if you are mounting it outdoors. Follow these steps to ground the
antenna in accordance with national electrical code instructions.
