Coaxial cable Rangeful HF400 TNC male to TNC male, 50 Ω, full copper, 3 m

Rangeful HF400 coaxial cable with TNC male connectors on both ends is a 3 meter, 50 Ω cable built with full copper conductors and a shielded dielectric structure. It is intended for RF and antenna connections where low loss, stable impedance and mechanical reliability are required. The cable construction supports consistent signal transfer across common RF bands, making it suitable for test benches, wireless devices and amateur radio rigs.

Advantages

The full copper center conductor and continuous shielding provide improved conductivity and reduced insertion loss compared with plated alternatives. The TNC male connectors deliver threaded coupling for enhanced mechanical stability in field and lab environments. The 50 Ω impedance and consistent construction reduce reflections and standing waves, helping preserve signal integrity over the 3 m length.

Suitable for

• Connecting antennas to receivers and transmitters
• Laboratory and test equipment setups
• Amateur (ham) radio installations
• Wireless base stations and RF modules
• Portable and field measurement systems

Key specifications

• Impedance: 50 Ω
• Connector type: TNC male — both ends
• Conductor material: full (solid/stranded) copper
• Length: 3 m
• Shielding: braided and foil shielding for reduced interference
• Typical application: RF and antenna signal transmission

How to use

Ensure both equipment connectors are clean and match the TNC female interfaces before making connections. Tighten the TNC threaded coupling by hand until snug; avoid over-tightening with tools to prevent damage to the connector body. Route the cable to avoid sharp bends and points of mechanical stress, maintaining a bend radius consistent with typical RF coaxial specifications. When used in measurement setups, keep cable runs as short as practical and verify connections to minimize mismatch and loss.

Usage recommendations

Store the cable coiled without tight loops and protect connector ends with dust caps when not in use. For best RF performance, inspect connectors periodically for corrosion and replace the cable if outer jacket damage or exposed shielding is observed.
