Cisco CAB-L240-15-SM-TM RF Antenna Cable

The Cisco CAB-L240-15-SM-TM is a 15-foot (approximately 4.57 m) LMR-240 RF antenna cable designed for use with compatible Cisco industrial routers and wireless networking equipment. It provides a reliable connection between equipment using an SMA male interface and an antenna or other RF component using a TNC male interface.

Designed for outdoor installations, the CAB-L240-15-SM-TM is specified as an outdoor direct-burial (DB) cable, making it suitable for applications where RF equipment and antennas need to be positioned at a distance from the router. Its 15-foot length provides additional installation flexibility while helping simplify antenna placement in industrial and infrastructure environments.

Key Features

• 15 ft (4.57 m) length for flexible antenna installation and equipment positioning
• LMR-240 RF cable construction for cellular and wireless networking applications
• SMA male to TNC male connectors for connection between compatible Cisco equipment and antennas
• Straight SMA(m)-STR and TNC(m)-STR interfaces
• Outdoor direct-burial (DB) type for appropriate outdoor installation scenarios
• Designed for use with supported Cisco industrial routers and wireless access points
• Suitable for RF connections across frequencies used by compatible cellular and wireless systems

RF Performance

The cable has a specified RF loss of approximately 1.1 dB at 0.7 GHz, increasing to 1.4 dB at 1.0 GHz, 1.8 dB at 1.7 GHz, 2.2 dB at 2.4 GHz and 2.3 dB at 2.7 GHz. These characteristics should be considered when designing an RF installation, particularly where cable length and overall signal budget are important.

Typical Applications

The CAB-L240-15-SM-TM is suitable for extending the RF connection between compatible Cisco industrial networking equipment and externally mounted antennas. It can be used in industrial, infrastructure, transportation, utility and other distributed wireless deployments where equipment and antennas cannot be installed directly beside one another.

As a Cisco-supported RF accessory, the CAB-L240-15-SM-TM provides a practical cable option for installations requiring a 15-foot SMA-to-TNC connection and outdoor direct-burial cable construction.
