Coaxial cable Rangeful HF240 TNC Male–TNC Male 50 Ω 12 m

Rangeful HF240 TNC Male–TNC Male 50 Ω 12 m is a 12-metre coaxial cable designed for RF signal transmission between devices with TNC connectors. The cable maintains a characteristic impedance of 50 ohms along its length, enabling consistent signal transfer for antenna extensions, router connections and short RF links. Both ends terminate in male TNC connectors for threaded, reliable mechanical and electrical contact with TNC-equipped equipment.

Advantages

The cable provides a stable 50 Ω impedance to minimise reflections and mismatch losses across the length. Threaded TNC male connectors offer secure mechanical retention and good electrical contact in environments where vibration or movement may be present. The 12 m length allows flexible placement of antennas or equipment without the need for additional adapters, while the coaxial construction shields the inner conductor from external interference to preserve signal integrity.

Suitable for

• Extending antenna connections for routers, access points and radios
• Connecting TNC-equipped test equipment and measurement devices
• Temporary or fixed short-range RF links in lab and field setups
• Applications requiring a 50 Ω transmission line with threaded connectors

Key specifications

• Impedance: 50 ohm characteristic impedance suitable for RF systems
• Length: 12 metres of coaxial cable
• Connector type: TNC male on both ends with threaded coupling
• Cable construction: coaxial design with inner conductor, dielectric, shield and jacket
• Primary use frequency range: suitable for typical RF applications (antenna, router, radio connections)

How to use

Ensure both devices to be connected use TNC female sockets and are powered off before installation. Align the TNC male connector with the mating TNC female socket and engage the threaded coupling, turning until hand-tight to secure the connection; avoid over-tightening. Route the cable to minimise sharp bends and avoid kinks; maintain bend radii greater than the cable diameter to preserve impedance characteristics. After connection, power up the equipment and verify signal levels and SWR (where applicable) to confirm proper operation.

Usage recommendations

For best performance, keep cable runs as short as practical and avoid coiling excess cable tightly. Use proper strain relief near connector ends and protect connectors from moisture and corrosion when used outdoors. If higher frequencies or lower loss are required, evaluate cable loss specifications and consider alternative cable types or shorter runs.
