Coaxial Cable Rangeful HF400 TNC Male to TNC Female 50 Ω 25 m

Rangeful HF400 TNC Male to TNC Female 50 Ω 25 m is a 25-meter coaxial cable designed for RF and antenna connections that require TNC terminations. The cable implements a 50-ohm impedance suitable for most radio-frequency systems and test equipment. Built with a shielded transmission line and moderate flexibility, it balances signal loss and ease of routing for installations over medium distances.

Advantages

The cable offers consistent 50 Ω impedance, reliable TNC male to TNC female connectivity and a shielded construction that reduces electromagnetic interference. Its 25 m length covers medium-range runs without the need for additional joins, and the moderate flexibility simplifies routing in racks, conduits and along antenna mast installations. The TNC terminations provide threaded mechanical security for applications subject to vibration.

Suitable for

• RF and antenna connections between transceivers and antennas
• Laboratory and test-bench setups with TNC interfaces
• Network links and signal distribution in radio installations
• Temporary or semi-permanent installations requiring moderate flexibility

Key specifications

• Characteristic impedance: 50 ohm
• Cable length: 25 m
• Connector type: TNC male to TNC female (threaded)
• Cable construction: shielded coaxial
• Typical use: RF transmission lines for antennas and test equipment

How to use

Connect the TNC male end to the corresponding TNC female jack on the transmitter or test instrument, and secure the TNC female end to the antenna or receiving device by threading the connectors until hand-tight plus a small additional quarter-turn if required for mechanical stability. Avoid sharp bends and kinks along the 25 m run; maintain a bend radius no smaller than the cable manufacturer's recommended radius to prevent increased insertion loss. If routing through conduits or entry points, ensure connectors are protected from crushing or exposure to moisture.

Usage recommendations

For best performance, keep cable runs as short as practical, inspect connectors for clean contacts before installation, and avoid coiling excess length tightly. When used in outdoor or humid environments, consider additional weatherproofing at connector junctions and periodic inspection to preserve low-loss transmission.
