Coaxial cable Rangeful RP-SMA male to RP-SMA female HF400 12 m 50 Ω full copper

Coaxial cable Rangeful RP-SMA male to RP-SMA female HF400 12 m 50 Ω full copper is a radio-frequency jumper cable designed for low-loss signal transmission between devices with RP-SMA terminations. The HF400 coax construction combined with a full copper center conductor ensures consistent characteristic impedance of 50 Ω over the 12 m length, making it suitable for antenna extensions, test leads and connections in wireless setups. The cable provides a stable RF path for frequencies commonly used in amateur radio, Wi‑Fi equipment and other RF systems requiring RP-SMA interfaces.

Advantages

The HF400 construction with a full copper core reduces insertion loss and preserves signal integrity across the 12 m span while maintaining flexibility for routing. RP-SMA male to RP-SMA female terminations offer compatibility with devices that use reversed polarity SMA interfaces without requiring adapters. The 50 Ω impedance matches standard RF equipment to minimise reflections, and the robust shielding of HF400 helps limit external interference in typical indoor and sheltered outdoor environments.

Suitable for

• Antenna extensions and repositioning for routers, access points and outdoor antennas
• Test and measurement setups in labs and workshops where RP-SMA connectors are required
• Amateur radio and short-range wireless installations using 50 Ω systems
• Connecting wireless modems, repeaters and IoT gateways that accept RP-SMA terminations

Key specifications

• Cable type: HF400 coaxial cable
• Connector A: RP-SMA male
• Connector B: RP-SMA female
• Length: 12 m
• Characteristic impedance: 50 Ω
• Center conductor: full copper
• Typical use: RF signal transmission for antenna and test connections

How to use

Connect the RP-SMA male end to the corresponding RP-SMA female socket on the device and attach the RP-SMA female end to the antenna or accessory with an RP-SMA male socket. Ensure connectors are threaded until fully seated but avoid over-tightening to prevent damage to threads or connector dielectric. Route the cable to avoid sharp bends and places where it may be crushed; keep a bend radius appropriate for HF400 coax to preserve electrical characteristics. For temporary test setups, secure the cable to prevent movement that could stress connectors.

Usage recommendations

For best performance, use this 50 Ω cable in installations where impedance matching matters; avoid exposing the cable to sustained direct sunlight or heavy mechanical strain. When used outdoors, provide basic weather protection at connector junctions. Periodically inspect connector integrity and re-seat connections if signal degradation is observed.
