Coaxial cable Rangeful HF240 BNC male to SMA male 50 Ω, 3 m

Rangeful HF240 coaxial cable with BNC male to SMA male connectors, 50 Ω impedance and 3 m length is designed for RF and antenna connections where a reliable 50 ohm path is required. The cable provides signal transmission between devices with BNC and SMA ports and is suitable for test equipment, antennas, and general-purpose RF connections in laboratory, field and installation environments. The construction balances flexibility and shielding to minimise insertion loss and maintain consistent impedance over its length.

Advantages

The cable offers a standard 50 Ω impedance for compatibility with RF systems and test instruments that require matched transmission lines. BNC male and SMA male connectors allow direct connection between common coaxial ports without adapters. A 3 m length gives extended reach while remaining manageable for bench use or temporary field setups. The cable’s shielding and connector termination are designed to reduce signal reflections and provide consistent performance across typical RF frequency ranges.

Suitable for

• Connecting measurement instruments such as spectrum analyzers and signal generators to devices with BNC or SMA ports
• Linking antennas to receivers or transmitters where a BNC-to-SMA interface is required
• Laboratory test setups and prototype measurements requiring a reliable 50 Ω feed line
• Field and installation tasks where moderate cable length and flexibility are needed

Key specifications

• Impedance: 50 Ω
• Connector A: BNC male
• Connector B: SMA male
• Length: 3 m
• Cable type: coaxial RF cable designed for low-loss signal transmission

How to use

Inspect connectors and cable for damage before use. Align the BNC male connector with the corresponding BNC female port and push and twist until it locks. Screw the SMA male connector onto the SMA female port by hand until finger-tight; avoid overtightening with tools to prevent connector damage. Route the cable to avoid sharp bends and kinks, maintaining bend radii recommended for coaxial cables to preserve performance. After connection, verify signal continuity and expected signal levels using appropriate test equipment.

Usage recommendations

For best results, use the cable within typical RF frequency ranges supported by its construction and avoid exceeding bend radius or exposing connections to moisture. When connecting sensitive test instruments, confirm impedance matching and connector compatibility to reduce reflections and measurement error. Store coiled loosely to prevent permanent deformation.
