Coaxial cable Rangeful HF400 BNC male to SMA male 12 m, 50 Ω, full copper

Rangeful HF400 coaxial cable with BNC male to SMA male connectors, 12 meters long, 50 Ω impedance and full-copper conductors is designed for reliable RF signal transmission between devices that use BNC and SMA ports. The continuous copper core provides stable conductivity and helps reduce insertion loss over longer runs. The cable is intended for test equipment, antennas, radios and laboratory setups where a durable, predictable RF connection is required.

Advantages

The full-copper inner conductor and shield provide consistent electrical conductivity and improved shielding compared with copper-clad alternatives. A 50 Ω characteristic impedance matches standard RF test and communication equipment, reducing reflections and ensuring better power transfer. The 12 m length allows flexible placement of devices without additional adapters, while the BNC male to SMA male connector pair supports straightforward connections between commonly used RF interfaces.

Suitable for

• Connecting antennas to receivers or transmitters
• Linking signal generators, spectrum analyzers and other RF test instruments
• Connecting radios, transceivers and repeaters during setup or testing
• Laboratory and bench-top RF experiments where stable impedance is required

Key specifications

• Length: 12 m
• Characteristic impedance: 50 Ω
• Connector A: BNC male
• Connector B: SMA male
• Conductor: solid full copper core
• Cable type: HF400 (flexible coaxial cable construction)

How to use

Ensure both devices are powered off before connecting the cable to avoid accidental damage or transient signals. Align the BNC male connector with the female BNC receptacle and push-and-twist until it locks. Thread the SMA male connector onto the SMA female port by hand, tightening gently to finger-tight; avoid over-torquing. Route the cable to minimize sharp bends and avoid running it parallel to noisy power lines or large transformers to reduce interference. After installation, power on equipment and verify signal continuity and expected RF levels using appropriate test instruments.

Usage recommendations

For optimal long-term performance, avoid kinking the cable and maintain a minimum bend radius consistent with flexible HF400 coaxial construction. Periodically inspect connectors for corrosion or dirt and clean connector interfaces with suitable, non-abrasive tools. When using in test environments, label cable ends to track connections and prevent accidental mismatch of impedance or connectors.
