Coaxial cable Rangeful HF400 TNC Male to TNC Female 50 Ω, 20 m

Rangeful HF400 coaxial cable with TNC male to TNC female connectors is a 20 meter, 50 Ω RF cable designed for reliable signal transmission between radio equipment and antennas or test instruments. The cable uses HF400-type coaxial construction to provide stable characteristic impedance and reduced insertion loss over medium distances, making it suitable where TNC terminations are required.

Advantages

The cable delivers a consistent 50 ohm impedance and low attenuation for improved RF performance across VHF and UHF frequency ranges. TNC male to TNC female connectors offer a threaded coupling for secure, vibration-resistant connections. The HF400 construction balances flexibility and shielding effectiveness, enabling easier routing in installations while maintaining signal integrity.

Suitable for

• Connecting antennas to transceivers and receivers with TNC interfaces
• Laboratory and test bench RF setups requiring 50 Ω feedlines
• Amateur radio and commercial radio installations over medium distances
• Temporary and permanent installations where a 20 m length is appropriate

Key specifications

• Characteristic impedance: 50 Ω
• Length: 20 m
• Connector type: TNC male to TNC female (threaded)
• Cable type: HF400-style coaxial
• Intended use: RF signal transmission and antenna feedline

How to use

Connect the TNC male end to the device or antenna port that accepts a TNC female connector, and attach the TNC female end to the matching male port on the opposite device. Ensure the threaded couplings are hand-tightened to provide a secure connection without over-torquing. Route the cable to avoid sharp bends and kinks; maintain a bend radius consistent with HF400 coaxial construction to prevent deformation. For permanent installations, secure the cable along its path using appropriate clamps or cable ties placed at regular intervals.

Usage recommendations

Confirm compatibility of TNC terminations and 50 Ω impedance with connected equipment before installation. Avoid prolonged exposure to direct sunlight and moisture where possible; if used outdoors, consider additional environmental protection or conduit. Periodically inspect connector integrity and cable shielding, and replace the cable if the dielectric or outer jacket shows significant wear.
