Coaxial cable Rangeful HF400 BNC male–BNC male 50 Ω, 20 m

Rangeful HF400 coaxial cable with BNC male to BNC male connectors is a 50 Ω, 20 m RF cable designed for reliable signal transmission between BNC-equipped devices. The cable is intended for applications requiring impedance matching, low signal loss and flexible deployment over medium distances. It is suitable for lab measurements, broadcast patching and CCTV monitoring where a 20-meter run with standard BNC terminations is needed.

Advantages

The cable provides consistent 50 Ω impedance for minimized reflections and improved RF performance. Flexible construction allows easier routing in confined spaces and temporary setups. BNC male-to-male terminations ensure quick push‑and‑twist connections to common test instruments, video equipment and RF modules. The 20 m length offers extended reach without the need for additional couplers while maintaining reasonable insertion loss for short- to medium-range links.

Suitable for

• Connecting test equipment (signal generators, spectrum analyzers, oscilloscopes) to DUTs
• Broadcast patching in studio or field setups
• CCTV camera systems and video monitoring with BNC interfaces
• Laboratory measurements and educational RF experiments

Key specifications

• Characteristic impedance: 50 Ω
• Connector type: BNC male to BNC male
• Length: 20 m
• Cable type: coaxial RF cable suitable for low-loss signal transmission
• Typical use: RF, video and test instrumentation connections

How to use

Connect one BNC male end to the output or input connector of the first device and push the mating BNC female, then twist the coupling nut to secure the connection. Route the cable to avoid sharp bends, excessive tension or sources of strong electromagnetic interference. For measurement tasks, ensure both connected instruments are set to compatible impedance and input/output levels to prevent mismatch. Inspect connectors for proper seating before powering sensitive equipment.

Usage recommendations

For optimal performance, keep cable runs as short as practical and avoid tight coils or kinks. If used outdoors or in exposed environments, protect connectors from moisture and mechanical strain. When precise RF measurements are required, verify cable condition and consider using calibration or reference cables to account for insertion loss at the frequencies of interest.
