Coaxial cable Rangeful HF240 SMA Male to SMA Female 50 Ω, 12 m

Rangeful HF240 SMA Male to SMA Female 50 Ω, 12 m is a 12-metre coaxial cable designed to provide a direct RF connection between devices that use SMA connectors. The cable maintains a characteristic impedance of 50 ohms and is suitable for HF, VHF and UHF frequency ranges where a longer run is required while preserving signal integrity for antennas, radio modules, test instruments and routers with SMA interfaces.

Advantages

The HF240 cable combines a consistent 50 Ω impedance with a 12 m length to enable stable RF transmission over an extended distance. Its SMA male to SMA female connector configuration allows straightforward mating with a wide range of antenna ports and measurement equipment without adapters. The cable construction minimizes return loss and preserves signal levels across HF/VHF/UHF bands, making it appropriate for field setups and bench testing where connector compatibility and cable length are important.

Suitable for

• Connecting external antennas to routers, modems and radio modules with SMA ports
• Temporary or semi-permanent field installations requiring a 12 m run
• Bench testing and measurement with RF instruments that use SMA interfaces
• HF, VHF and UHF amateur radio and professional communication setups

Key specifications

• Impedance: 50 Ω
• Length: 12 m
• Connector A: SMA male
• Connector B: SMA female
• Intended frequency ranges: HF / VHF / UHF
• Typical use: RF signal transmission between SMA-interface devices

How to use

Align the SMA male connector with the SMA female receptacle and gently screw the connectors together by hand until finger-tight; avoid excessive torque. Route the cable to minimize sharp bends and avoid kinks or tight wraps around objects to prevent impedance disruption. When disconnecting, unscrew the coupling nut by hand while supporting the mating connector to avoid stressing the installation. For measurement tasks, keep connector interfaces clean and free of debris to maintain accurate readings.

Usage recommendations

For best performance, avoid running the coaxial cable parallel to power cables or strong RF sources that may introduce interference. Use appropriate strain relief at connector ends if the cable is subject to movement, and inspect connectors periodically for wear or corrosion, especially in outdoor or high-humidity environments.
