Flexible length for indoor or outdoor routing andConnector type specified; use with compatible RP‑SMA devices.

## Long description

Rangeful RP-SMA Male to RP-SMA Male HF400 Full Copper 20 m is a 20-meter RF coaxial cable designed for signal extension and routing in Wi‑Fi, cellular and radio installations that require RP‑SMA terminations. The cable uses an HF400 full copper conductor and a coaxial structure optimized for low-loss transmission across common wireless frequency bands. Both ends are fitted with RP‑SMA male connectors to match devices and antennas that use reverse-polarity SMA interfaces.
Advantages
The HF400 full copper conductor provides improved conductivity and consistent impedance compared with lower-quality cores, reducing insertion loss over the 20 m run. The RP‑SMA male connectors ensure proper mating with reverse‑polarity SMA sockets and maintain mechanical stability for antenna connections. The cable jacket is flexible enough for indoor routing and installation while keeping the conductor and dielectric protected from mechanical stress.
Suitable for
Extending antenna connections for Wi‑Fi access points and routers
Connecting external antennas to cellular modems and gateways
Temporary or fixed radio and IoT device installations requiring RP‑SMA terminations
Laboratory setups and signal testing where a 20 m run is needed
Key specifications
Cable length: 20 m
Conductor material: full copper HF400
Connector ends: RP‑SMA male to RP‑SMA male
Cable type: RF coaxial
Characteristic impedance: 50 Ω
Jacket: flexible protective outer sheath suitable for indoor routing
How to use
Use the cable to extend or route RF connections between devices and external antennas that accept RP‑SMA male terminations. Before installation, verify that both devices use reverse‑polarity SMA interfaces to ensure compatibility. Route the cable to avoid sharp bends and excessive tension; maintain a minimum bend radius recommended for HF400 coaxial constructions. Secure connectors by hand-tightening and avoid over-torquing; if using a torque wrench, apply the manufacturer’s recommended torque for RP‑SMA connectors.
Usage recommendations
For best performance, keep cable runs as short as practical and avoid running coax alongside power cables to minimize interference. For outdoor exposure use, protect connectors and exposed cable sections with appropriate weatherproofing materials. Regularly inspect connectors for corrosion or damage and replace the cable if visible wear compromises signal quality.
