Cisco Aironet Dual-band Dipole Antenna

(AIR-ANT2524DB-R, AIR-ANT2524DG-R, and

AIR-ANT2524DW-R)

This document describes and provides specifications for the Cisco Aironet high-performance, dual-band

dipole antenna. The antenna operates in both the 2.4-GHz and 5-GHz frequency bands and is designed

for use with Cisco Aironet 2.4-GHz and 5-GHz radio products that have dual-band reverse-polarity TNC

(RP-TNC) antenna ports. The antenna has a nominal gain of 2 dBi in the 2.4-GHz frequency band and

4 dBi in the 5-GHz frequency band. The three antennas covered in this document are electrically the

same. They differ physically by the color of the radome, which is specified by the product part number

shown in Table 1.

System Requirements

This antenna is designed for use with Cisco Aironet access points that support simultaneous operation

in the 2.4 GHz band and the 5 GHz band and that have dual-band antenna ports, labeled as such in orange

text.

Features

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.

Installing the Antenna

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.

Follow these steps to install the antenna.

Step 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.

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

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

Step 4 Tighten the antenna by hand. Do not use a wrench or any other tool to tighten the antenna.

Step 5 Adjust the antenna’s articulating joint to the desired position.
