Coaxial cable Rangeful HF240 BNC male to SMA male 50 Ohm, 5 m

Rangeful HF240 coaxial cable with BNC male to SMA male connectors, 50 Ohm impedance and 5 m length provides a fixed, low-reflection connection for RF signal transmission between devices with BNC and SMA ports. The cable is designed for general-purpose radio frequency use, offering a straightforward link between test equipment, antennas and radio systems in laboratory and field environments.

Advantages

The cable combines a common BNC interface with a compact SMA connection on a single 50 Ohm coaxial core, ensuring electrical compatibility for most RF test and monitoring setups. Its 5 m length allows flexible placement of equipment while maintaining predictable signal attenuation. The construction minimizes impedance mismatch and maintains mechanical reliability through standard male BNC and SMA fittings suitable for repeated connections.

Suitable for

• Connecting test instruments (spectrum analyzers, signal generators) to devices with SMA or BNC ports
• Linking antennas and radio receivers/transmitters in amateur and professional radio setups
• Temporary lab and field RF measurements where a fixed-length 50 Ohm cable is required
• Signal routing between converters, filters and other RF modules with BNC/SMA interfaces

Key specifications

• Impedance: 50 Ohm
• Connector A: BNC male
• Connector B: SMA male
• Length: 5 m
• Cable type: coaxial, RF-grade
• Typical applications: RF test, antenna connections, signal routing

How to use

Inspect connectors for cleanliness and secure that both mating ports are free from debris before connecting. Align the BNC male with the BNC female on the device and push then twist the coupling nut until it locks. For the SMA male, gently screw the connector onto the SMA female until finger-tight; avoid over-tightening. Route the 5 m cable to prevent sharp bends or kinks and keep it away from strong sources of electromagnetic interference where possible. For measurements, allow the setup to stabilise before recording results.

Usage recommendations

Use the cable as a fixed interconnect rather than for frequent mechanical stress; avoid repeated flexing near the connector ends. Clean connector mating surfaces with a lint-free cloth or suitable cleaning tool if needed. When used in precision measurement contexts, account for insertion loss and, if necessary, use calibration or reference measurements to correct for cable attenuation.
