Coaxial cable Rangeful HF400 TNC male to SMA male, 50 Ω, flexible HF400, length 2 m

Rangeful HF400 coaxial cable with TNC male to SMA male connectors is a flexible 50 Ω RF lead designed for reliable signal transmission between devices with TNC and SMA ports. The 2 m length provides convenient reach for connections between test equipment, antenna systems and radio modules while the HF400 construction balances flexibility and shielding to support stable high‑frequency performance in constrained routing environments.

Advantages

The cable combines a consistent 50 Ω impedance with precision TNC and SMA male terminations to minimise reflection and insertion loss across common RF bands. Its flexible HF400 jacket and inner construction make it easier to route in tight spaces compared with rigid coax types, while the durable connector housings ensure repeated mating cycles without significant performance degradation.

Suitable for

• Connecting test and measurement instruments to antennas or RF transceivers
• Prototyping and bench setups where SMA and TNC interfaces are used
• Temporary or permanent links in radio, telemetry and wireless installations
• Routing in confined spaces where flexibility is required

Key specifications

• Characteristic impedance: 50 Ω
• Connector type: TNC male to SMA male
• Cable type: flexible HF400 coaxial
• Length: 2 m
• Typical use: RF signal and antenna connections

How to use

Align the TNC male and SMA male connectors with the corresponding female ports on your devices and hand‑tighten until finger‑snug; avoid excessive torque to prevent damage to the connector threads and mating surfaces. Route the cable to minimise sharp bends and avoid tight kinks—maintain gentle curvature to preserve RF performance. For installation near sources of mechanical stress, secure the cable with appropriate clips or ties without compressing the jacket.

Usage recommendations

Inspect connector interfaces before mating to remove dust or debris. For critical RF measurements, keep cable runs as short as practical and avoid proximity to large power cables or noisy electronics. When disconnecting, hold the connector body rather than pulling on the cable to extend service life.
