Cisco Aironet Dual Band MIMO Low Profile Ceiling Mount Antenna (AIR-ANT2451NV-R)
78-19022-02
Installation Notes
•
Install the antenna away from microwave ovens and 2-GHz cordless phones. These products can
cause signal interference because they operate in the same frequency range as the device to which
your antenna is connected.
Choosing a Mounting Location
The antenna should be mounted clear of any obstructions to the sides of the radiating elements.
Generally, the higher an antenna is above the floor, the better it performs. If possible, find a mounting
place directly above your wireless device to ensure that any additional lead-in cable can be as short as
possible.
Tools and Equipment Required
You need the following tools and equipment, which are not provided.
•
A suitable hole cutter capable of creating a 1-in. (2.54-cm) hole in a suspended ceiling tile.
Note
We recommend a hole saw, which is available in most home improvement centers and hardware
stores.
•
A step ladder high enough to access your ceiling safely.
Installing the Antenna
The antenna is installed to a suspended ceiling tile with a supplied 1 in. (2.54-cm) plastic nut. See
Figure 1
for details.
The antenna terminates with an RP-TNC connector after a short, 3-ft. (91-cm) cable. The mating
connector to the antenna is an appropriate RP-TNC connector.
