Coaxial cable Rangeful HF240 BNC male to SMA male 50 Ω 12 m

Rangeful HF240 coaxial cable BNC male to SMA male 50 Ω 12 m provides a shielded, fixed-length RF connection between devices with BNC and SMA ports. The 50-ohm impedance and standard male connectors make it suitable for signal transfer in test benches, radio setups and antenna systems where a reliable coax link is required. The 12 m length allows for flexible placement of equipment while keeping a single continuous cable run without adapters.

Advantages

The cable combines common BNC and SMA male terminations with a consistent 50 Ω characteristic impedance to minimise reflections and preserve signal integrity across its length. Its construction includes shielding to reduce electromagnetic interference and a durable outer jacket for mechanical protection during repeated handling. The fixed-length design removes the need for intermediate adapters and reduces connector loss points.

Suitable for (tasks / use cases)

• Connecting RF test instruments to devices under test that use BNC and SMA ports
• Linking radio transceivers and external antennas in lab or field setups
• Signal routing in communication benches, monitoring rigs and educational labs
• Temporary or semi-permanent installations where a 12 m coax run is required

Key specifications

• Impedance: 50 ohm characteristic impedance for RF compatibility
• Connectors: BNC male on one end and SMA male on the other end
• Length: 12 metres fixed length cable
• Cable type: shielded coaxial construction to reduce EMI
• Mechanical: flexible jacket suitable for routing in test and field environments

How to use

Inspect connectors and the cable jacket for visible damage before use. Align the BNC male with the BNC female socket and push-and-twist until the bayonet locks; align the SMA male with the SMA female and screw gently by hand until finger-tight. Avoid over-tightening SMA connectors with tools unless specified torque is required by equipment guidelines. Route the cable to avoid sharp bends and pinching, keeping bend radii moderate to preserve RF performance.

Usage recommendations

For best results, use the cable within the operating frequency range supported by the connected devices and avoid exposing it to mechanical strain, excessive moisture, or prolonged UV exposure. When connecting sensitive test equipment, keep cable runs as short as practicable and verify connector tightness before measurements to minimise insertion loss and reflection.
