Coaxial Cable Rangeful HF400 TNC Male to SMA Male, 50 Ω, Flexible, 7 m

Rangeful HF400 coaxial cable with TNC male to SMA male connectors is a 50 Ω flexible RF cable designed for reliable signal transfer over a 7 meter length. The HF400 construction provides moderate flexibility while maintaining impedance matching for use in test benches, lab setups and antenna extensions. The cable is intended for connecting equipment with TNC and SMA ports where a longer, routable lead is needed without compromising RF performance.

Advantages

The HF400 cable combines a flexible dielectric and shielding structure to preserve 50 ohm impedance across the run, reducing reflections and signal loss for typical RF frequencies compatible with TNC and SMA interfaces. Factory-installed TNC male and SMA male connectors ensure secure mechanical and electrical connections. The 7 m length allows convenient placement of devices or antennas while the flexible jacket simplifies routing through racks and enclosures.

Suitable for

• Laboratory test setups and measurement benches
• Connecting radios, transceivers or RF modules with TNC and SMA ports
• Antenna extensions where a 7 m lead is required
• Prototyping and temporary RF system configurations

Key specifications

• Impedance: 50 Ω
• Connector types: TNC male to SMA male
• Cable construction: flexible HF400 coaxial
• Length: 7 m
• Typical applications: RF signal transfer, antenna feeding, test instrumentation

How to use

Route the cable between devices ensuring connectors match the TNC and SMA ports on the equipment. Hand-tighten the SMA and TNC connectors to the recommended torque for those connector types where possible; avoid over-tightening. Keep the cable run free from sharp bends — maintain a gentle bend radius consistent with flexible HF400 construction to prevent deformation of the interior dielectric or shielding. Where connectors or ports are exposed to dust or moisture, use protective caps when the cable is disconnected.

Usage recommendations

For optimal RF performance, avoid kinking the cable and minimise repeated flexing at the connector interfaces. Use short jumper segments or adaptors only when necessary, and verify system SWR or return loss on installation if used in precision measurement setups.
