Coaxial cable Rangeful TNC Male–TNC Male HF240 50 Ω, 0.3 m

Rangeful HF240 coaxial cable with TNC male connectors on both ends is a short, 50 Ω RF interconnect designed for reliable signal transmission in compact installations. At 0.3 m length, this cable is intended for connecting TNC-equipped antennas, radios, test instruments and repeaters where minimal cable run and stable impedance are required. The construction suits RF and microwave frequency ranges commonly used in communication and measurement setups.

Advantages

The cable delivers consistent 50 Ω impedance along its length to minimise signal reflections and loss when used in RF applications. TNC male connectors provide secure threaded coupling for vibration-resistant connections in equipment racks and field devices. Its short 0.3 m length reduces unnecessary attenuation and preserves signal integrity in bench setups and tight-space installations.

Suitable for

• Connecting TNC-equipped antennas to radios and repeaters
• Interfacing test instruments and measurement equipment on a bench
• Short runs inside equipment racks and communication cabinets
• Field deployments where a compact, threaded RF lead is needed

Key specifications

• Characteristic impedance: 50 Ω
• Connector type: TNC male – TNC male (threaded)
• Length: 0.3 m
• Cable series: HF240 (flexible coaxial construction for RF use)
• Typical application range: RF and microwave signal interconnects

How to use

Ensure both mating connectors and cable ends are clean and free from debris before connection. Hand-thread the TNC male connectors onto the corresponding female ports until finger-tight, then use a torque wrench if the equipment manufacturer specifies a torque value for optimal coupling. Avoid excessive bending near the connector ends and maintain a gentle bend radius to prevent deformation of the coaxial structure. For temporary test setups, keep the cable run short and straight to reduce insertion loss.

Usage recommendations

Use this short 0.3 m Rangeful HF240 cable where minimal signal path length and a secure threaded connection are priorities. Store the cable coiled without tight loops and avoid sharp kinks. For critical measurement work, verify connection integrity and check VSWR or insertion loss with appropriate test equipment.
