Coaxial cable Rangeful RP‑SMA male to RP‑SMA female HF400 50 Ω 1 m

Flexible HF400 coaxial cable by Rangeful with RP‑SMA male to RP‑SMA female connectors provides a 1 m low‑loss RF link with 50 Ω impedance. The cable is built with full copper conductors and a dielectric optimized for radio frequency transfer, offering consistent performance for antenna extensions, Wi‑Fi and IoT devices, and other RF equipment that require RP‑SMA terminations. This product is intended as an inline jumper or extension where a short, durable connection is needed between RP‑SMA terminated components.

Advantages

The HF400 construction uses full copper inner and outer conductors to reduce insertion loss and maintain signal integrity across common RF frequency ranges. The RP‑SMA male to RP‑SMA female configuration allows for correct gender‑specific mating in systems that use reverse polarity SMA connectors, preventing accidental mismatches. The 50 Ω characteristic impedance ensures compatibility with most RF devices, and the 1 m length provides a practical balance between reach and minimal additional attenuation.

Suitable for

• Antenna extensions for routers, access points and wireless modules
• Connecting radio transceivers, receivers and test equipment with RP‑SMA ports
• Wi‑Fi, IoT and telemetry installations requiring short, flexible RF leads
• Lab and prototyping setups where easy‑to‑change RP‑SMA jumpers are needed

How to use

Align the RP‑SMA male and RP‑SMA female connectors by matching the connector bodies and gently screw them together until hand‑tight; avoid using excessive force or tools which can deform connector threads. Route the cable to minimise sharp bends and avoid kinks; maintain a bending radius recommended for flexible HF400 coaxial cable to prevent increased loss. When installing between devices, ensure both ends are clean and free of debris and that connected equipment is powered down if required by the device manufacturer before mating connectors.

Usage recommendations

For best RF performance, keep the cable length as short as practical for the application, protect connectors from moisture and mechanical stress, and avoid running the coaxial cable parallel to power lines to reduce interference. Regularly inspect connectors for wear and replace the cable if physical damage or significant loss is observed.
