Coaxial cable Rangeful HF240 TNC male to TNC female, 50 Ω, 7 m

Rangeful HF240 TNC male to TNC female coaxial cable is a 7 m, 50 Ω RF cable designed to provide a standardized connection between TNC-equipped devices. The cable features a TNC male connector at one end and a TNC female connector at the other, offering a secure threaded coupling for applications where reliable RF signal transfer and mechanical stability are required. With a moderate length of 7 meters, the cable is intended for in-room or short-run installations that require flexibility and consistent impedance matching.

Advantages

The cable offers consistent 50 Ω impedance suitable for RF applications, minimizing reflection and signal loss when used with matching equipment. The threaded TNC connectors improve mechanical stability and reduce the risk of accidental disconnection compared with non-threaded connectors. The 7 m length provides extra reach for connecting devices without introducing unnecessary slack, and the single-cable design simplifies routing in installations where a TNC male to TNC female interface is required.

Suitable for

• Connecting routers, modems and wireless access points with TNC ports
• Linking external antennas to radio equipment and repeaters
• Temporary or permanent connections in test benches and RF measurement setups
• Interfacing TNC-equipped instrumentation and signal analyzers

Key specifications

• Characteristic impedance: 50 Ω
• Cable length: 7 m
• Connector types: TNC male to TNC female (threaded)
• Intended use: RF signal transmission and interconnection of TNC-equipped devices

How to use

Connect the TNC male end to the device with a female TNC receptacle and screw the connector until it is hand-tight to ensure reliable mechanical coupling. Attach the TNC female end to the corresponding male connector on the other device in the same manner. Route the cable to avoid sharp bends and excessive compression; maintain bend radii recommended for coaxial cables to preserve electrical performance. For test or measurement use, ensure proper equipment grounding and follow the instrument manufacturer's guidelines for cable connections.

Usage recommendations

Use the cable within its intended frequency and power ranges for low-loss RF connections. Avoid repeated connector mating beyond typical usage to preserve connector longevity. Store the cable coiled without kinks, and inspect connectors for corrosion or damage before critical measurements or installations.
