Omni-directional network antenna Cisco Aironet RP-TNC, dual-band 2.4/5 GHz, max gain 5 dBi

Omni-directional Cisco Aironet network antenna with RP-TNC male connector, designed for dual-band operation at 2.4 GHz and 5 GHz. The antenna provides broad, even coverage using an omnidirectional radiation pattern and offers a maximum gain of 5 dBi (3 dBi at 2.4 GHz). It is supplied as a single unit and is intended for indoor deployments where access points or routers accept RP-TNC connectors. The AIR-ANT2535SDW-RS model incorporates a built-in EEPROM for antenna self-identification with compatible Cisco access points, allowing automatic recognition of antenna type and gain by the wireless controller.

Advantages

The antenna supports dual-band WLAN operation, enabling use with both 2.4 GHz and 5 GHz networks while maintaining a compact form factor suitable for ceiling- or wall-mounted indoor installations. Its omnidirectional pattern delivers consistent coverage in horizontal planes, reducing dead zones around the access point. The RP-TNC male connector allows straightforward connection to access points and external radios that accept RP-TNC. The EEPROM-equipped variant provides automatic identification and simplifies controller-based configuration when used with supported Cisco Aironet and Catalyst access points.

Suitable for

• Extending indoor Wi‑Fi coverage in offices, classrooms, and public spaces
• Use with Cisco Aironet 1600, 2600, 3600, 3700 and Catalyst 9120AXE series access points
• Replacement or upgrade of existing RP-TNC equipped antennas on compatible APs and routers
• Deployments requiring a low-profile, omnidirectional antenna for general coverage

Key specifications

• Frequency bands: 2.4 GHz and 5 GHz
• Maximum gain: 5 dBi (overall), 3 dBi at 2.4 GHz
• Radiation pattern: omnidirectional
• Connector type: RP-TNC male
• Mounting: indoor ceiling or wall mounting compatibility
• EEPROM: built-in EEPROM for antenna identification (model with self-identification)
• Form factor: single-unit antenna, compact profile for indoor use

How to use

Install the antenna by securely connecting the RP-TNC male connector to the matching RP-TNC female port on the access point or router. Position the antenna vertically for typical omnidirectional coverage; mounting on a ceiling or wall at a central location will maximize horizontal reach. If using the EEPROM-equipped version with supported Cisco access points, verify the access point recognizes the antenna in the controller or device interface so the controller can apply correct antenna type and gain settings. Ensure the device is powered off or follow hot-swap guidance from the access point manufacturer before connecting or disconnecting antennas.

Usage recommendations

Place the antenna at a central, unobstructed indoor location and avoid close proximity to large metal objects or dense partitions to preserve omnidirectional coverage. Use the EEPROM-enabled model with supported Cisco Aironet and Catalyst access points to enable automatic antenna identification and correct gain reporting in controller-managed environments.
