Coaxial cable Rangeful TNC Male–TNC Male HF400 50 Ω, full copper, 12 m

Rangeful HF400 coaxial cable with TNC male to TNC male connectors is a 12 m, 50 Ω cable constructed with full copper conductors intended for RF signal transmission and antenna connections. The cable is designed to reduce insertion loss and preserve signal integrity across VHF and UHF frequencies, providing a dependable connection between transceivers, test equipment and antennas where TNC terminations are required.

Advantages

The full copper center conductor and carefully designed dielectric ensure low attenuation and consistent characteristic impedance across the cable length. TNC male connectors on both ends provide a secure threaded connection that resists vibration and improves mechanical stability compared with push-fit terminations. The cable's overall construction emphasizes durability for repeated handling and reliable electrical performance in indoor and sheltered outdoor installations.

Suitable for

• Connecting amateur radio transceivers to antennas and tuners
• Linking RF test equipment and measurement devices
• Wireless system patching and antenna installations in VHF/UHF bands
• Temporary or permanent interconnects in lab and workshop environments

Key specifications

• Characteristic impedance: 50 Ω
• Conductor material: full copper center conductor
• Connector type: TNC male – TNC male (threaded)
• Cable type: HF400 coaxial
• Length: 12 m
• Application frequency range: suitable for VHF and UHF RF use

How to use

Route the cable avoiding sharp bends and tight loops; maintain a bend radius larger than the cable diameter to prevent deformation and preserve impedance characteristics. Screw the TNC male connectors securely onto the mating TNC female ports by hand, ensuring threads engage smoothly and the connection is snug but not over-tightened. For test setups, connect one end to the signal source and the other to the measurement device or antenna, then verify power levels and SWR as applicable before full operation.

Usage recommendations

For optimal performance, avoid installing the cable in direct exposure to prolonged moisture or extreme weather unless additional protective conduit or sealing is used. Inspect connectors periodically for corrosion or mechanical wear and replace the cable if outer jacket damage exposes the braid or inner conductor.
