Coaxial cable Rangeful HF400 15m, BNC male to SMA male, full copper, 50 Ω

Rangeful HF400 15m coaxial cable with BNC male to SMA male connectors is a 50 Ω RF cable constructed from full copper conductors and shielding. The 15 metre length provides extended reach for connecting test instruments, antennas, transceivers and other RF equipment that use BNC or SMA interfaces. The cable is designed for low-loss signal transmission in applications where a 50 Ω impedance match is required.

Advantages

The full copper conductors and shielding ensure consistent conductivity and effective screening against interference. The fixed impedance of 50 Ω supports matched RF systems and reduces reflections. Durable connector fittings—BNC male on one end and SMA male on the other—allow direct interfacing between devices with those ports without additional adapters. The 15 m length balances reach with manageable signal attenuation for many amateur radio, lab and antenna applications.

Suitable for

• Connecting radios, transceivers and receivers with BNC and SMA ports
• Laboratory RF test setups and signal measurements
• Antenna connections where a 50 Ω coaxial link is required
• Prototyping and bench work requiring a reliable 15 m RF cable

Key specifications

• Impedance: 50 Ω
• Length: 15 m
• Connector A: BNC male
• Connector B: SMA male
• Conductor and shielding material: full copper
• Intended use: RF signal transmission and testing

How to use

Inspect connectors and cable for visible damage before use. Firmly attach the BNC male connector to the BNC socket by aligning and engaging the bayonet coupling and ensure the SMA male connector is threaded and tightened to the SMA female port without overtightening. Route the cable to avoid sharp bends, excessive tension or kinks that could increase loss or damage the jacket. Where measurement accuracy is required, make connections with the equipment powered down and verify impedance matching in the system.

Usage recommendations

For best performance, keep cable runs as short and direct as practical, avoid coiling tightly, and prevent repeated flexing at the connector junctions. Use this 50 Ω coaxial cable for RF paths where a BNC-to-SMA connection is needed and verify compatibility with the frequency range and power levels of your equipment.
