Coaxial cable Rangeful HF400 TNC Male to TNC Female, 50 Ohm, full copper, 3 m

Coaxial cable Rangeful HF400 TNC Male to TNC Female, 50 Ohm, full copper, 3 m is a 3-meter RF cable with TNC male connector on one end and TNC female connector on the other. The cable has a characteristic impedance of 50 ohms and a full-copper central conductor, designed to provide consistent signal transmission for RF and antenna connections. It is intended for use with equipment that requires TNC interfaces and 50-ohm matching, such as routers, radio devices, test instruments and other RF installations.

Advantages

The Rangeful HF400 cable combines a full-copper conductor with 50-ohm characteristic impedance to reduce insertion loss and maintain signal integrity across typical RF frequencies. TNC male-to-female terminations provide reliable threaded coupling for secure mechanical and electrical contact. The 3 m length offers flexibility in equipment placement while keeping attenuation within predictable limits for short to medium runs.

Suitable for

• Connecting antennas to routers, modems and radio transceivers
• Interfacing test equipment and measurement setups that use TNC connectors
• Temporary or semi-permanent RF installations with 50-ohm matching
• Extension leads between TNC-equipped devices in laboratories and workshops

Key specifications

• Connector A: TNC male
• Connector B: TNC female
• Characteristic impedance: 50 Ω
• Conductor material: full copper (solid or stranded copper conductor)
• Cable length: 3 m
• Intended use: RF signal and antenna connections

How to use

Ensure both mating connectors are free of dust and damage before connection. Align the TNC male and TNC female connectors, engage the threaded coupling by hand and tighten gently to secure the connection; avoid over-tightening to prevent damage to the connectors. Route the cable to minimize sharp bends and kinks; maintain gentle bend radii to prevent increased loss or mechanical stress. When disconnecting, loosen the coupling thread fully before pulling connectors apart.

Usage recommendations

For best RF performance, use this 3 m Rangeful HF400 cable only within applications that require 50-ohm impedance and TNC terminations. Avoid routing near high-power electrical lines or sources of interference, and inspect connectors periodically for corrosion or wear. For long-term outdoor installations or environments with moisture exposure, consider additional environmental protection such as weatherproof boots or sealed enclosures.
