Coaxial cable Rangeful BNC male to SMA male HF240 50 Ω, 0.5 m

Rangeful HF240 coaxial cable with BNC male to SMA male connectors, 50 Ω impedance and 0.5 m length is a short RF interconnect for linking devices with BNC and SMA ports. The cable is designed for applications requiring 50-ohm characteristic impedance to maintain signal integrity and minimise reflections. Its compact length makes it suitable for bench setups, measurement rigs and antenna feedlines where a low-loss, reliable connection between BNC and SMA interfaces is needed.

Advantages

The cable provides impedance-matched 50 Ω transmission to reduce VSWR and signal reflections between connected devices. BNC male and SMA male connectors offer secure mechanical mating and straightforward installation. The short 0.5 m length reduces insertion loss and helps keep cable routing tidy on test benches or inside equipment racks. Construction is intended for consistent RF performance across common VHF/UHF frequency ranges used in radio, test instruments and antennas.

Suitable for

• Connecting test equipment (spectrum analyser, signal generator) with mixed BNC and SMA ports
• Short antenna feed or jumper between radio transceiver and adapter
• Laboratory and bench setups requiring compact RF interconnects
• Temporary connections during installation, calibration, or troubleshooting

Key specifications

• Characteristic impedance: 50 Ω
• Connector types: BNC male to SMA male
• Length: 0.5 m
• Cable type: coaxial, HF240 construction
• Typical use: RF signal transmission for VHF/UHF bands and laboratory equipment

How to use

Ensure both mating connectors are free of debris and aligned before engagement. Push the BNC connector onto the BNC jack and twist to lock; screw the SMA male onto the SMA female until hand-tight, avoiding excessive torque. Route the cable to avoid sharp bends and close proximity to strong interference sources. For best RF performance, keep cable length as short as practical and use the cable only within its intended frequency range and power handling limits.

Usage recommendations

Store the cable coiled loosely to prevent kinks, and inspect connector interfaces regularly for wear or contamination. When connecting to sensitive measurement equipment, verify impedance matching and check for unexpected losses with appropriate test instruments.
