Coaxial cable Rangeful RP-SMA Male to RP-SMA Male HF400 50 Ω 25 m

Flexible HF400 coaxial cable by Rangeful with RP-SMA male to RP-SMA male connectors, 50 Ω impedance and 25 m length. Designed for RF and antenna connections where low loss and flexibility are needed, this cable provides reliable signal transfer and easy routing in installations. The construction balances attenuation and mechanical pliability to suit indoor and sheltered outdoor runs between transceivers, routers, antennas and test equipment.

Advantages

The cable features a 50-ohm characteristic impedance that matches most RF systems and antenna ports, reducing reflections and preserving signal integrity. Its HF400-type dielectric and shielding offer lower insertion loss relative to thinner coax types while maintaining flexibility for cable management. Gold-plated RP-SMA male connectors ensure consistent contact and corrosion resistance for long-term reliable connections. With a 25 m length, the cable supports extended routing without the need for multiple joiners, reducing potential points of signal degradation.

Suitable for

• Connecting ham radio transceivers to external antennas
• Linking routers or Wi‑Fi equipment with RP‑SMA antenna ports
• Temporary or permanent RF test setups and measurement chains
• Indoor or sheltered outdoor antenna installations where flexibility is required

Key specifications

• Cable type: HF400 coaxial
• Connectors: RP‑SMA male to RP‑SMA male
• Impedance: 50 Ω
• Length: 25 m
• Conductor and shielding: multi-layer shield with braided outer conductor for improved screening
• Connector plating: corrosion-resistant gold plating on contact surfaces
• Flexibility: medium — suitable for routing along walls and through cable channels

How to use

Before connecting, ensure both equipment ports are RP‑SMA female compatible and power to transmitters is turned off. Align the RP‑SMA male connectors with the mating ports and engage gently, avoiding excessive force; hand-tighten until secure. Route the cable to avoid sharp bends, kinks or areas of heavy mechanical stress. If the installation is outdoors, keep connections sheltered from direct weather exposure and use appropriate sealing methods if necessary. After installation, test signal levels and adjust antenna positioning or cable routing as required to optimise performance.

Usage recommendations

For best results, avoid repeated tight bending at the same point and minimise the use of additional adapters. When running near power lines or noisy electronics, maintain separation to reduce interference. If permanent outdoor installation is required, use weatherproof enclosures for connectors and consider a higher-grade outdoor-rated coax if exposed to UV and moisture long-term.
