Coaxial cable Rangeful SMA Male to SMA Female HF400 20 m, 50 Ω, full copper

Rangeful HF400 coaxial cable with SMA male to SMA female connectors, 20 meters long and 50 Ω impedance, is engineered for RF signal transmission and antenna connections. The cable uses full copper conductors to provide consistent conductivity and reduce insertion loss over distance. Its flexible construction makes routing and installation easier in temporary or permanent wireless setups while maintaining stable electrical contact at the SMA interfaces.

Advantages

The cable provides low-loss RF transfer across VHF/UHF ranges thanks to its HF400-style coaxial design and full copper center conductor. Flexible outer jacket and consistent 50 Ω characteristic impedance ensure predictable performance with antennas, scanners, ham radio transceivers and test instruments. SMA male to SMA female terminations offer secure mechanical mating and straightforward compatibility with equipment using SMA connectors.

Suitable for

• Connecting antennas to transceivers and receivers
• Portable and fixed ham radio installations
• RF testing and measurement setups with SMA interfaces
• Scanner, base station and wireless equipment cabling

Key specifications

• Length: 20 m
• Impedance: 50 Ω
• Center conductor material: full copper
• Connector types: SMA male to SMA female
• Cable type: HF400-style coaxial
• Jacket: flexible outer sheath suitable for routing

How to use

Inspect connectors and cable ends before use to ensure clean, undamaged contact surfaces. Route the 20 m coaxial cable avoiding sharp bends and tight loops; maintain bend radii consistent with flexible HF400 cables to preserve impedance and minimize loss. Connect the SMA male end to the device requiring a male plug and the SMA female end to the corresponding female socket, tightening by hand and, if available, to the recommended torque for SMA connectors using a torque wrench. For temporary installations, secure the cable to prevent strain on connectors; for permanent runs, use appropriate clips or ties that do not compress the jacket excessively.

Usage recommendations

For best performance, keep cable runs as short as practical, avoid running parallel to high-power electrical lines, and protect exposed SMA connections from moisture and mechanical stress. When used with sensitive receivers or in measurement applications, verify insertion loss and VSWR characteristics in your setup and replace the cable if any visible damage or connector wear is observed.
