Coaxial cable Rangeful HF240 SMA male to SMA male, 3 m, pure copper

Rangeful HF240 SMA male to SMA male coaxial cable, 3 m, with a pure copper conductor provides a straightforward RF connection between devices with SMA ports. The cable is built for low signal attenuation and consistent impedance, making it suitable for linking antennas, routers, radio equipment, measurement instruments and other SMA-equipped components in test setups and deployed systems.

Advantages

The pure copper core of the Rangeful HF240 ensures good electrical conductivity and reduced insertion loss compared with lower-grade conductors. The 3-meter length offers flexibility for typical bench and field arrangements without excessive slack. Both ends terminate in SMA male connectors that provide a secure threaded coupling and reliable mechanical contact. The cable construction balances flexibility and shielding to limit bending stress while maintaining stable RF performance across common antenna and signal frequency ranges.

Suitable for

• Connecting antennas to routers, modems, and radio transceivers with SMA ports
• Laboratory and test-bench RF measurements and prototypes
• Temporary and permanent installations where a 3 m SMA-to-SMA lead is needed
• Signal and data links between SMA-equipped devices

Key specifications

• Length: 3 meters
• Connector type: SMA male to SMA male (threaded)
• Conductor material: pure copper core
• Cable type: coaxial with shielding designed for RF use
• Typical use: antenna and RF device interconnection
• Flexibility: designed for moderate bending and routing in typical installations

How to use

Align the SMA male connectors with the SMA female ports on the devices, then engage the threaded coupling by hand until snug. Avoid over-tightening with tools to prevent connector or seal damage. Route the cable to minimize sharp bends and tight loops; maintain gentle curves and secure the cable to prevent strain on the connectors. For measurement tasks, connect the cable between instrument and device, verify continuity and signal levels, and adjust the setup as needed for calibration or testing.

Usage recommendations

For optimal performance, keep cable runs as short as practical and avoid repeated tight bending near the connector ends. Inspect connectors for debris before mating, and use torque-limited tools only if specified by connected equipment. When used outdoors or in higher-vibration environments, consider additional strain relief or protective routing to preserve connector integrity and consistent signal transmission.
