Coaxial cable Rangeful HF240 7m with SMA male to SMA male connectors, copper

Rangeful HF240 is a 7-meter coaxial cable with SMA male to SMA male connectors and a copper conductor, designed for RF signal transmission between devices with SMA interfaces. The cable supports antenna connections, test instruments and laboratory setups where a flexible, medium-length RF link is required. Its construction provides consistent impedance and stable contact across the full cable run, enabling dependable transfer of radio-frequency signals in measurement and communication applications.

Advantages

The cable combines a continuous copper conductor and SMA male terminations to ensure low contact resistance and predictable electrical characteristics. Its 7 m length allows flexible routing without intermediate adapters, and the SMA-to-SMA configuration is compatible with a wide range of antennas, transceivers and RF test equipment. The cable jacket and connector assembly are designed to maintain mechanical flexibility and repeatable connector seating for reliable signal paths over repeated connections.

Suitable for

• Connecting external antennas to routers, modems and cellular gateways with SMA ports
• Linking RF signal generators, spectrum analyzers and network analyzers in test setups
• Laboratory experiments and prototyping that require a medium-length SMA coaxial link
• Temporary or semi-permanent installations where flexibility and ease of routing matter

Key specifications

• Cable length: 7 meters
• Connector type: SMA male to SMA male
• Center conductor material: copper
• Impedance: compatible with standard SMA equipment (50 ohm systems)
• Typical use: RF signal transmission, antenna and test instrument connections

How to use

Inspect connector threads and cable ends before installation to ensure cleanliness and no visible damage. Align each SMA male connector with the mating SMA connector and hand-tighten the threaded coupling until snug; avoid excessive torque to prevent connector damage. Route the cable to minimize sharp bends and kinks; maintain bend radii consistent with flexible coaxial cable practice. For test and measurement use, connect one end to the signal source and the other to the measurement instrument or antenna, and verify signal continuity and expected levels with appropriate equipment.

Usage recommendations

For optimum performance, keep connector interfaces clean and protected when not in use, avoid repeated overtightening, and maintain gentle cable bends to preserve impedance characteristics. Use the cable within the frequency and power limits of connected devices and verify compatibility with 50 ohm systems to prevent reflections or signal loss.
