Coaxial cable Rangeful HF240 TNC male to TNC male 50 Ω, 10 m

Rangeful HF240 TNC male to TNC male 50 Ω, 10 m is a coaxial cable designed for RF signal transmission between devices with TNC interfaces. The cable provides a fixed 10 m length and a 50 ohm characteristic impedance to support stable signal transfer in communication and measurement setups. It is fitted with TNC male connectors on both ends to ensure a secure threaded connection for antennas, radio equipment, test instruments and repeaters.

Advantages

The cable combines a standard 50 Ω impedance and precision TNC male terminations to minimise reflections and maintain signal integrity across the run. Its fixed 10 m length removes the need for on-site assembly or splicing, while the threaded TNC connectors provide mechanical stability in environments where vibration or movement may occur. The construction is intended to offer consistent performance for RF frequencies where a 50 Ω coaxial link and TNC interface are required.

Suitable for

• Connecting antennas to radio transceivers and receivers
• Linking test instruments and measurement equipment with TNC ports
• Interfacing repeaters, scanners and other communication devices
• Temporary or permanent RF installations requiring a 10 m 50 Ω cable

Key specifications

• Connector type: TNC male on both ends
• Impedance: 50 ohm
• Length: 10 meters
• Cable type: coaxial RF cable (single run, fixed length)
• Application: RF signal transmission for communication and measurement

How to use

Align the TNC male connectors with the mating TNC female ports on each device and engage the threaded coupling by hand until finger-tight; avoid excessive force to prevent damage to connector threads. Route the cable to minimise sharp bends, kinks or strain; maintain bend radii appropriate for RF coaxial cables to preserve impedance characteristics. For long-term installations, secure the cable along its run using appropriate clamps or ties that do not pinch the jacket. Before critical measurements or system commissioning, verify continuity and check for excessive insertion loss with appropriate test equipment if available.

Usage recommendations

For best performance, avoid repeated mating cycles on the same connector interfaces and protect connector ends from dirt and moisture when not connected. Use the cable within the environmental conditions and frequency ranges suitable for 50 Ω TNC connections, and inspect periodically for jacket damage or connector wear.
