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

Rangeful HF240 is a 3 m coaxial cable with a BNC male connector on one end and a BNC female connector on the other, built to a 50 Ω impedance standard. It is intended for RF signal routing, test and measurement setups, video signal distribution and connections between devices with BNC interfaces. The cable length and connector combination allow straightforward linking of laboratory instruments, broadcast equipment, CCTV cameras and amateur radio transceivers while maintaining consistent characteristic impedance for minimal signal reflections.

Advantages

The cable provides stable 50 Ω impedance along its length to support RF and video signals with reduced mismatch losses. The BNC male to BNC female configuration enables quick, threaded push-and-twist connections that are commonly used across test equipment and video devices. With a 3 m length, the cable offers moderate reach suitable for bench setups and short cable runs without introducing excessive signal attenuation. The construction balances flexibility for routing and sufficient shielding for reliable signal integrity in typical indoor installations.

Suitable for

• Connecting signal generators, spectrum analyzers and oscilloscopes to DUTs and adapters
• Linking broadcast and video equipment, including mixers, monitors and cameras
• CCTV camera to DVR/NVR connections in short to medium cable runs
• Amateur radio transceiver antenna tuners and low-power RF test setups

Key specifications

• Impedance: 50 Ω
• Length: 3 m
• Connector A: BNC male
• Connector B: BNC female
• Typical application: RF, test equipment, video signal transmission
• Cable type: coaxial with shielding for reduced interference

How to use

Align the BNC male connector with the mating BNC female jack, push the connector in and twist until it locks to ensure a secure mechanical and electrical contact. Avoid excessive bending near the connector ends; route the cable with gentle curves to maintain consistent impedance and minimize strain. When disconnecting, grip the connector body, twist and pull to release rather than pulling on the cable jacket.

Usage recommendations

For best performance, use the cable within indoor environments and avoid exposure to prolonged moisture or direct sunlight. Keep cable runs as short as practical for RF applications to reduce insertion loss, and verify connectors are free of debris before mating. For higher-frequency or critical test measurements, ensure connectors and instruments are calibrated and consider using a higher-grade cable if specified by the measurement tolerance.
