The Cisco AIR‑ANT2535SDW‑RS is a compact, dual-band omnidirectional dipole antenna engineered for indoor enterprise Wi-Fi 6 environments. It operates on both 2.4 GHz and 5 GHz bands, with peak gains of 3 dBi and 5 dBi respectively. Uniquely, the “RS” model includes an integrated EEPROM for self-identification by Cisco Catalyst 9120AXE access points (running IOS‑XE 17.4.1+), automating deployment and minimizing configuration errors.
Featuring a rugged, articulated RP‑TNC male connector that allows both 360° rotation and 90° tilt, it installs effortlessly on ceiling or wall-mounted APs. Its minimalistic white radome makes it virtually invisible in modern interior spaces. The antenna is entirely passive—no power or configuration needed—yet delivers predictable, Cisco-tuned RF performance in dense client environments like offices, classrooms, healthcare facilities, and retail spaces.
| Access Point Model | Antenna Port Requirement | Notes |
| Catalyst 9120AXE | RP‑TNC Port A (purple) | RS auto-identified, R manual only |
| Aironet 1600/2600/3600/3800 | RP‑TNC ports | Functions normally (EEPROM not used) |
