Cisco CAB-L240-20-SM-TM= 20-ft LMR240 Cable | SMA/TNC Connector — CAB-L240-20-SM-TM=

Maintain cleaner RF paths over extended distances with Cisco’s 20-ft (3 m) ultra low loss LMR240 cable. This assembly is designed for installations where every dB matters, helping reduce attenuation compared with higher-loss cabling in the same class. The LMR240 construction supports more reliable signal delivery between compatible devices, while the SMA/TNC connector pairing simplifies integration across common Cisco and RF equipment environments. For infrastructure teams, the value is straightforward: fewer compromises on signal quality when equipment placement cannot be ideal. Use it to connect radios, antennas, and related network hardware in racks, enclosures, and distributed installations where cable length is unavoidable. The 20-ft reach gives you practical routing flexibility without forcing a move to heavier, more expensive custom assemblies. Choose this cable when the application calls for a precise fit, known connector types, and a low-loss path that supports stable performance. It is a purpose-built accessory for deployments that demand consistency, not guesswork. Ideal For Connecting radios to antennas in rack-mounted or remote placements Routing RF links where standard cable length would add excess loss Integrating Cisco-compatible equipment with SMA and TNC interfaces Supporting lab, branch, or distributed network installations Why This Product 1 Lower-loss path than standard coax in longer runs 2 Pre-terminated SMA/TNC connectors reduce installation friction 3 20 ft length supports flexible equipment placement 4 Cisco-specified assembly for compatible infrastructure deployments
