## Summary description

Flexible coaxial cable Rangeful HF400 with BNC male to SMA male connectors, 50 ohm impedance and 3 m length. Designed for RF signal transmission between devices with BNC and SMA ports, it suits antennas, radio equipment, test instruments and connectivity in lab or field setups. The HF400 construction provides flexibility for tight routing while maintaining stable 50 Ω performance.

## Long description

Rangeful HF400 coaxial cable with a BNC male connector on one end and an SMA male connector on the other is a 3 m, 50 Ω flexible RF cable designed for connecting equipment with BNC and SMA ports. The HF400 construction emphasises bendability for routing in confined spaces while maintaining stable characteristic impedance and low loss across typical RF frequencies. This cable is intended for signal transmission between antennas, radio transceivers, test instruments and other RF components where a compact, flexible interconnect is required.
Advantages
The cable combines a widely used BNC interface with an SMA termination, enabling easy interoperability between devices that use different connector standards. Its flexible HF400 jacket and inner construction reduce stress on connectors when routed in tight spaces, while the 50 Ω impedance supports consistent signal transfer for RF applications. The 3 m length provides sufficient reach for many bench and field setups without excessive slack.
Suitable for
 Connecting antennas to radio receivers or transceivers with differing connector types
 Linking test equipment such as spectrum analyzers, signal generators, and oscilloscopes to DUTs
 Laboratory and bench setups requiring flexible routing and reliable 50 Ω impedance
 Field installations where a moderate-length, flexible RF lead is needed
Key specifications
 Connector A: BNC male
 Connector B: SMA male
 Characteristic impedance: 50 Ω
 Cable type: flexible HF400 coaxial
 Length: 3 m
 Application: RF signal transmission between BNC and SMA ports
How to use
Ensure both mating connectors are clean and free of debris before making connections. Align the BNC male with the BNC female and push and twist as required to engage the bayonet lock; align the SMA male and gently screw it to the SMA female until hand-tight. Avoid over-tightening the SMA connector with tools; hand-tight is generally sufficient for reliable electrical contact. Route the cable to minimise sharp bends and avoid kinking; use gentle curves consistent with the flexible HF400 construction to maintain impedance integrity.
Usage recommendations
For consistent RF performance, keep the cable length appropriate to the setup, avoid crushing or sharp bending near connectors, and inspect connectors periodically for wear or corrosion. Use proper torque when mating SMA connectors if specified by equipment documentation, and store the cable coiled without tight loops when not in use.
