Cisco AIR-ANT2535SDW-R Aironet Short Dual-Band Omni Antenna

This document describes the Cisco Aironet AIR-ANT2535SDW-R and AIR-ANT2535SDW-RS antennas and provides electrical specifications and mounting instructions. The antenna operates over the 2.4 GHz and 5 GHz Wi-Fi bands and is designed for indoor use with the Cisco Aironet 1600, 2600, 3600, 3700, and Cisco Catalyst 9120AXE series access points. The antenna utilizes an omnidirectional radiation pattern to achieve a broad coverage area.

The AIR-ANT2535SDW-RS antenna includes circuitry to enable self-identification of the antenna by the Cisco access points. The antenna has a built-in EEPROM that can be read by the AP to automatically configure the antenna type and gain in the wireless controller.
