Coaxial cable Rangeful HF240 50 Ohm 1 m with TNC male to TNC female connectors

Rangeful HF240 50 Ohm coaxial cable is a 1-meter RF interconnect fitted with a TNC male connector on one end and a TNC female connector on the other. The fixed-length cable is engineered to maintain consistent 50 Ohm impedance for short signal runs between radio equipment, antennas, test instruments and networking devices that use TNC interfaces. The construction is intended to deliver repeatable electrical performance and stable transmission for laboratory setups, field repairs and permanent or semi-permanent installations requiring a reliable TNC-to-TNC link.

Advantages

This coaxial cable offers a standard 50 Ohm characteristic impedance to match RF systems and minimize reflection losses. The 1 m length provides a compact, easy-to-route connection without excess slack. TNC male and female connectors provide secure threaded coupling for improved mechanical stability compared with push-on connectors, and the fixed assembly reduces variability compared with detachable leads. The cable’s construction supports consistent insertion loss and stable performance across the intended frequency range for typical TNC-connected equipment.

Suitable for

• Connecting radio transceivers to antennas or antenna extensions
• Linking RF test instruments and measurement equipment in labs
• Interfacing networking devices and wireless infrastructure with TNC ports
• Short patch or jumper runs inside cabinets, racks or field enclosures

Key specifications

• Characteristic impedance: 50 Ohm
• Length: 1 meter
• Connector types: TNC male — TNC female
• Cable type: coaxial RF cable designed for TNC terminations
• Typical use: short interconnects and jumper applications for RF systems

How to use

Inspect connectors and cable for visible damage before use. Thread the TNC male connector onto the mating TNC female jack until hand-tight, taking care not to cross-thread. When connecting test equipment or antennas, ensure both ends are properly seated and the mating surfaces are clean to maintain signal integrity. Avoid sharp bends and excessive strain on the cable; maintain the manufacturer’s recommended bend radius where possible. For disconnection, unthread the connector fully before pulling to prevent damage to threads or center contacts.

Usage recommendations

For optimal performance, use this 1 m 50 Ohm TNC-to-TNC cable in short-run applications where mechanical stability and consistent impedance are required. Avoid exposing the cable and connectors to prolonged moisture, corrosive environments or repeated mechanical stress. If used in measurement setups, allow fixtures and cables to stabilize thermally before taking precision readings to reduce small variations in signal level.
