The antenna has an articulated base that can be rotated 360 degrees at the connection point and from 0 to 90 degrees at its joint.
The AIR-ANT2524DW-RS antenna includes circuitry to enable self identification of the antenna by the Cisco Catalyst 91xx Series access points. The self identifying function is indicated by a purple band on the antenna. Ensure this antenna is connected to Port A on the AP, which is also designated by purple text around the RP-TNC connector. This antenna has a built-in EEPROM that can be read by the AP to automatically configure the antenna type and gain in the Wireless LAN Controller.

Caution: The AIR-ANT2524Dx-R series of antennas are dual-band antennas, meaning that they operate in both the 2.4 GHz and 5 GHz frequency bands. The AIR-ANT2524Dx-R series antennas have an orange ID band on them to indicate their dual-band functionality. Connect these antennas only to dual-band antenna ports, which are identified with orange text on Cisco Aironet access points. Using these antennas on Cisco Aironet access points that employ single-band antennas might result in lower performance.
To install the antenna:
  1. Verify that the connector to which you are connecting the antenna is a dual-band antenna port, identified by orange text on the access point. 

  2. Align the antenna connector with the RP-TNC connector on the access point. 

  3. Engage the antenna connector threads with the RP-TNC connector on the access point. 

  4. Hand tighten the antenna to the port using the metal knurled ring only.   

     Warning: Do not use the plastic body to tighten. This may damage the antenna. 

  5. Adjust the antenna articulating joint to the desired position.
