Coaxial cable Rangeful RP-SMA male to RP-SMA female HF400 30 m 50 Ω full copper

Rangeful HF400 coaxial cable with RP-SMA male to RP-SMA female connectors is a 30 m, 50 Ω RF cable designed for reliable signal transmission between antennas and radio equipment. The cable features full copper conductors and HF400 dielectric construction to maintain consistent impedance and low loss over a long run. The RP-SMA male to RP-SMA female termination provides a gender-reversed SMA-style connection commonly used in wireless devices, routers, ham radio setups and other RF systems requiring a 50 Ω interface.

Advantages

This coaxial assembly uses full copper inner and outer conductors combined with HF400 dielectric to offer stable electrical performance and reduced attenuation compared with lower-quality cables. The 30 m length enables flexible placement of antennas or radio units without the need for multiple adapters, while RP-SMA male to RP-SMA female connectors ensure compatibility with devices that use reversed-polarity SMA terminations. The cable’s consistent 50 Ω impedance supports match-sensitive RF applications, helping to minimize reflections and preserve signal integrity across the run.

Suitable for

• Connecting external antennas to wireless routers and access points with RP-SMA ports
• Ham radio stations and amateur radio transceivers requiring 50 Ω RP-SMA connections
• RF test setups and measurement rigs where a long, low-loss cable is needed
• Wireless communication devices and gateways with RP-SMA interfaces

How to use

Inspect both RP-SMA connectors for cleanliness and damage before making connections. Screw the RP-SMA male connector to the RP-SMA female port by hand until snug; do not overtighten with tools to avoid deforming the connector. Route the cable to avoid sharp bends and kinks, maintain a minimum bend radius as recommended for HF400 cable types, and secure the cable to prevent strain on the connections. When deploying outdoors or in exposed environments, use appropriate weatherproofing on the connector interfaces to prevent moisture ingress.

Usage recommendations

For best performance, keep cable runs as short as practical and avoid routing alongside large power cables to reduce potential interference. Periodically check connectors and cable integrity, and replace the cable if you observe significant wear, corrosion, or increased signal loss during operation.
