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.
