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

Rangeful HF400 coaxial cable with RP-SMA male to RP-SMA male connectors, 12 meters long and 50 Ω impedance is designed for RF signal transmission between antennas, routers, modems and radio equipment. The cable uses full copper conductors and a consistent 50 Ω characteristic impedance to minimise loss and preserve signal integrity across the run. Its 12 m length provides flexibility for indoor routing, outdoor antenna placement or extending existing antenna leads while maintaining stable connection performance.

Advantages

The cable construction features full copper center conductors and shielding to ensure low resistance and improved conductivity. RP-SMA male to RP-SMA male terminations provide secure threaded connections compatible with many wireless devices and antenna adapters. The HF400 dielectric and shielding geometry offer predictable attenuation characteristics over common cellular, Wi‑Fi and amateur radio bands. The flexible jacket supports easier installation through conduit, around corners or along walls without compromising the electrical properties.

Suitable for

• Connecting external antennas to routers, modems and cellular boosters
• Amateur radio and short-range RF test setups
• Extending antenna leads for better placement in indoor or outdoor installations
• Temporary or permanent links between RF devices requiring RP‑SMA male connections

Key specifications

• Length: 12 m
• Characteristic impedance: 50 Ω
• Connector type: RP‑SMA male to RP‑SMA male
• Conductor material: full copper
• Cable type: HF400 coaxial
• Typical use: RF/antenna cabling for cellular, Wi‑Fi and amateur radio bands

How to use

Ensure both devices use RP‑SMA male connectors or an appropriate adapter before connecting. Align the threaded RP‑SMA terminations and hand-tighten until snug; avoid over-tightening to prevent damage to the connector body. Route the 12 m cable to minimise sharp bends and avoid kinking; maintain bend radii recommended for coaxial cables to preserve impedance and reduce insertion loss. For outdoor routing, secure the cable with appropriate clips or mounts and avoid prolonged exposure to direct sunlight if the jacket is not UV-rated.

Usage recommendations

Verify frequency band compatibility of connected equipment and keep cable runs as short as practical for lowest loss. When installing outdoors, use weatherproofing at connectors and consider additional protection such as conduit or UV‑resistant jacketed cable for long-term exposures.
