Coaxial cable Rangeful HF240 50 Ω N male to SMA male, 2 m

Rangeful HF240 is a 2 m coaxial cable with a 50 Ω characteristic impedance, fitted with an N male connector on one end and an SMA male connector on the other. The cable is intended for RF signal transfer between devices that use different connector types, providing a short, reliable link for test benches, antenna feeds and inter-equipment connections. Its construction supports standard 50 ohm systems to minimise impedance mismatch in short runs.

Advantages

The cable combines a robust N male connector with a compact SMA male connector to bridge professional test equipment and smaller RF modules. Its 2 m length offers flexibility for typical bench setups without excessive loss from long runs. The 50 Ω impedance maintains system compatibility for antennas, transceivers and measurement instruments. The design emphasises mechanical stability and consistent electrical contact for repeated connect/disconnect cycles.

Suitable for

• Connecting laboratory test instruments to antenna systems or DUTs
• Linking RF modules with N and SMA interfaces during prototyping
• Temporary or semi-permanent antenna feeds where connector changeover is required
• Signal routing between transceivers, amplifiers and analyzers in 50 Ω systems

Key specifications

• Cable length: 2 m
• Characteristic impedance: 50 Ω
• Connector 1: N male
• Connector 2: SMA male
• Intended use: RF signal transmission in short runs

How to use

Align the N male and SMA male connectors with the corresponding device ports and engage them by hand; tighten the SMA connector to the device by turning its coupling nut until firm, and secure the N connector similarly if a retaining nut is present. Avoid over-tightening with tools to prevent damage to the connector threads. Route the cable to minimise sharp bends and avoid kinking; keep it clear of heat sources and strong electromagnetic interference where possible. When disconnecting, support the connector bodies to prevent stress on the cable itself.

Usage recommendations

Use the cable for temporary connections, laboratory setups and short antenna leads in 50 Ω systems. Inspect connectors for debris before use and replace the cable if mechanical damage or significant wear to the connector plating is observed. For longer runs or environments requiring lower loss, consider cables with larger diameter conductors or different materials appropriate to your installation.
