Note: The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.
This describes the Cisco Aironet high-performance, dual-band dipole antenna, and provides specifications and mounting instructions. 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 with 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 AIR-ANT2524Dx-R antennas covered in this document are electrically the same but differ physically by the color of the radome, which is specified by the product part number shown in Table 1. The AIR-ANT2524DW-RS antenna includes self-identifying circuitry.

Communications, Services, and Additional Information
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 in orange text.
The Self Identifying Antenna model AIR-ANT2524DW-RS= is supported only on Cisco Catalyst 9800 Series Wireless Controllers running an IOS-XE 17.4.1 release or a later release. This antenna model is not supported on Cisco AireOS Wireless Controllers.
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.
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.
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.
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.

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If the equipment causes interference to radio or television reception, which can be determined by turning the equipment off and on, users are encouraged to try to correct the interference by using one or more of the following measures:
■Reorient or relocate the receiving antenna.
■Increase the separation between the equipment and receiver.
■Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
■Consult the dealer or an experienced radio/TV technician for help.
