Coaxial cable Rangeful HF240 BNC male to SMA male 50 Ω, 0.3 m

Rangeful HF240 is a 0.3 m coaxial cable with BNC male to SMA male connectors and a characteristic impedance of 50 Ω. It provides a compact, solder-free RF connection for linking equipment with BNC and SMA ports. The cable is intended for short interconnections on test benches, radio equipment, antennas and measurement setups where a reliable 50 Ω path is required.

Advantages

The short 0.3 m length minimizes signal loss and reduces the risk of unwanted reflections in high-frequency lines. Gold-plated male BNC and SMA connectors ensure consistent contact and corrosion resistance without the need for additional adaptors. Constructed with a controlled-impedance inner conductor and shielding, the cable maintains RF performance across its intended frequency range and provides stable mechanical mating between devices.

Suitable for

• Connecting radio transceivers to test equipment
• Linking antennas or antenna feeds to measurement instruments
• Short signal runs on RF test benches and lab setups
• Interfacing devices with BNC and SMA female ports

Key specifications

• Connector type: BNC male to SMA male
• Impedance: 50 Ω
• Length: 0.3 m
• Cable construction: coaxial with braided shield
• Connector plating: corrosion-resistant (gold or equivalent finish)
• Applications: RF signal transmission, test & measurement, antenna connections

How to use

Align the BNC male connector with the female BNC jack and push until the bayonet locks; rotate the SMA male connector into the SMA female socket and hand-tighten until snug. Avoid over-tightening SMA connectors to prevent damage to threads. Route the cable to minimize sharp bends and avoid kinking; keep cable length as short as practical for the application to maintain optimal 50 Ω performance.

Usage recommendations

For accurate measurements and stable RF links, inspect connector mating surfaces for dirt or debris before use and replace the cable if the shielding or connectors show visible wear. Use the HF240 for short interconnects; for longer runs or higher-power applications, select a cable with appropriate length and power rating to maintain impedance and reduce loss.
