Coaxial RF Cable Rangeful HF240 SMA male to N male 50 Ω, 0.3 m

Rangeful HF240 SMA male to N male 50 Ω, 0.3 m is a short coaxial RF cable designed for reliable signal transmission between equipment with SMA and N connectors. The cable uses a 50 ohm characteristic impedance suitable for most RF test and antenna systems, and metal screw-type connectors provide secure mechanical and electrical contact. With a compact 0.3 m length, it is intended as a jumper cable for close-proximity connections, test benches, and installations where minimal loss and solid connector mating are required.

Advantages

The cable offers tight 50 Ω impedance matching to minimize reflections and maintain signal integrity in RF paths. Metal screw-type connectors ensure mechanical stability and repeatable electrical contact across multiple mating cycles. Its short 0.3 m length reduces insertion loss compared with longer leads and helps limit cable movement and microphonic effects in sensitive setups. The combination of SMA male and N male connectors provides compatibility between laboratory instruments, antennas, and RF equipment that use these common interfaces.

Suitable for (tasks / use cases)

• Connecting test equipment and measurement instruments in RF laboratories
• Joining antennas to receivers or transceivers with SMA and N interfaces
• Using as a jumper cable in RF racks and short-link installations
• Temporary or permanent links during antenna tuning and system alignment

Key specifications

• Characteristic impedance: 50 Ω
• Connector A: SMA male (threaded)
• Connector B: N male (screw-type)
• Length: 0.3 m
• Cable type: coaxial RF cable suitable for HF/VHF/UHF ranges

How to use

Inspect both connector interfaces for cleanliness and any visible damage before connecting. Align the SMA male and N male connectors with the mating ports and hand-tighten the N connector where applicable; use appropriate torque on threaded interfaces if specified by the connected equipment to avoid over-tightening. Route the cable without sharp bends or excessive tension to maintain consistent impedance and minimize strain on connectors. After installation, verify the link with a suitable RF test instrument to confirm expected signal levels and VSWR performance.

Usage recommendations

Store the cable coiled without kinks and protect connector ends with caps when not in use. For critical measurement tasks, periodically inspect and clean connectors with suitable, non-abrasive tools. Avoid exposing the cable to prolonged mechanical stress, strong solvents, or environments outside the cable's intended temperature and humidity ranges.
