Network Cable Cisco Aironet AIR-CAB020LL-R RP-TNC Plug Low-Loss 6m

The Cisco Aironet AIR-CAB020LL-R 20-Foot Low-Loss Cable Assembly is a 6 m RP-TNC to RP-TNC antenna cable designed to connect compatible Cisco Aironet access points to external antennas while minimizing signal loss. It supports reliable connectivity for wireless network installations and includes a 90-day limited hardware warranty.

Advantages

This low-loss cable reduces attenuation over its 6 m length, helping to preserve radio signal strength between the access point and the antenna. Both ends use RP-TNC connectors (one plug and one jack) for compatibility with select Cisco Aironet models, and the assembly is factory-terminated for easy installation.

Suitable for

• Extending the antenna connection of Cisco Aironet access points
• Indoor wireless deployments requiring low signal attenuation
• Temporary or permanent installations where a 6 m cable run is needed

How to use

Power down the access point if recommended by the device documentation. Connect the RP-TNC plug to the access point’s RP-TNC antenna connector and attach the RP-TNC jack to the external antenna. Route the cable to avoid sharp bends and sources of interference. After connections are secure, restore power and verify wireless performance.

Recommendations

For best performance, keep the cable run as short as practical, avoid tight bends or crushing the cable, and ensure connectors are tightened hand‑firm. Use this low‑loss cable when extending antenna placement to improve coverage while maintaining signal quality.
