Coaxial cable Rangeful HF400 TNC male to SMA male 10 m, 50 Ω, flexible

Rangeful HF400 coaxial cable with TNC male to SMA male connectors is a 10 meter, 50 Ω flexible RF cable designed for connecting equipment that uses TNC and SMA interfaces. The cable is intended for applications where longer runs and easy routing are required while maintaining impedance matching for reliable signal transfer between antennas, transceivers and test instruments.

Advantages

The flexible construction of the HF400 cable enables convenient installation in confined or complex routing paths without compromising electrical continuity. With TNC male and SMA male terminations, the cable offers compatibility with a wide range of radio, HF and VHF/UHF devices that accept these connectors. The 50 Ω characteristic impedance ensures proper matching for most RF systems, reducing reflections and preserving signal integrity over the 10 m length.

Suitable for

• Connecting antennas to transceivers or receivers with TNC and SMA interfaces
• Linking test instruments and measurement equipment requiring 50 Ω cabling
• HF, VHF and UHF radio installations where a flexible 10 m cable run is needed

Key specifications

• Length: 10 m
• Characteristic impedance: 50 Ω
• Connector A: TNC male
• Connector B: SMA male
• Cable type: flexible HF400 coaxial

How to use

Ensure both devices are powered off before connecting the cable. Align the TNC male connector with the TNC female socket and hand-tighten the coupling nut until secure; avoid overtightening. Align the SMA male connector with the SMA female socket and screw it on carefully to achieve a snug connection. Route the cable to avoid sharp bends and excessive strain; maintain bend radii appropriate for flexible coaxial cable to prevent damage. After installation, verify continuity and check system performance with an antenna analyzer or relevant test equipment as required.

Usage recommendations

Store and route the cable away from high-power AC cables and strong electromagnetic sources to minimize interference. For outdoor or exposed installations consider additional protective measures such as weatherproofing at connectors and securing the cable to prevent mechanical stress. Periodically inspect connectors for corrosion or looseness and retighten or replace as necessary to maintain reliable RF performance.
