The Cisco AIR‑ANT2535SDW‑R (non‑identifying) and AIR‑ANT2535SDW‑RS (self‑identifying) are short, dual‑band omnidirectional dipole antennas designed for enterprise indoor use. Operating across 2.4 GHz and 5 GHz bands with 3 dBi and 5 dBi peak gains respectively, they are optimized for high-density Wi‑Fi environments.
Key feature of the RS model is a built-in self-identifying EEPROM allowing automatic recognition by Cisco Catalyst 9120AXE access points running IOS‑XE 17.4.1+—simplifying deployment and ensuring RF consistency. Both models connect via RP‑TNC male connectors and offer vertical polarization with a compact form factor ideal for ceiling or wall-mounted installations where discretion and installation flexibility are required. They require no external power or software configuration.
| Access Point Model | Antenna Port Type | Notes |
| Catalyst 9120AXE | RP‑TNC port | RS auto-identified, R manual only |
| Aironet 1600, 2600, 3600, 3800 | RP‑TNC port | Both R and RS function normally |

We understand that making the right purchase decision is important. Below, you’ll find answers to common pre-sales questions about this product.
RS contains EEPROM for self-ID on Catalyst 9120AXE; R does not.
Yes—but EEPROM remains unused; antenna functions normally.
Typically 8–20 m, varying with AP RF settings and obstruction.
No; hand-tighten via the knurled RP‑TNC ring.
Yes—a purple band indicates RS version compatibility.
No; only supports 2.4 GHz and 5 GHz.
Yes—they’re compatible with RP‑TNC Cisco APs.
No—RF pattern and gain remain unchanged from R model.
Typically 8–20 meters, dependent on AP power and obstacles.
Yes-identifies Port A on metas, confirming correct deployment.
Cisco Catalyst 9120AXE models running IOS-XE 17.4.1+.
