Coaxial cable Rangeful RP‑SMA male to RP‑SMA male HF400 full copper 50 Ω 5 m

Flexible HF400 coaxial cable Rangeful RP‑SMA male to RP‑SMA male full copper 50 Ω 5 m is designed to transmit RF signals between devices with RP‑SMA interfaces. The cable features a full copper center conductor and copper shielding to ensure consistent electrical performance and reduced signal attenuation over a 5 meter length. It is suitable for connecting external antennas, routers, modems and RF test equipment where a reliable 50 Ω transmission line is required.

Advantages

The full copper conductor and braided copper shielding provide stable conductivity and improved shielding effectiveness compared with aluminum-clad alternatives, helping to minimize insertion loss and external interference. The HF400 dielectric and jacket construction offer a balance of flexibility and mechanical durability for routing in constrained spaces. RP‑SMA male connectors on both ends allow straightforward mating with devices that use reverse-polarity SMA interfaces without adapters.

Suitable for

• Connecting external antennas to routers and access points
• Linking modems, gateways and RF modules with RP‑SMA interfaces
• Laboratory and field testing of wireless devices and antenna measurements
• Upgrading or extending antenna cable runs where low loss is important

Key specifications

• Impedance: 50 Ω
• Length: 5 m
• Conductor: full copper center
• Shielding: braided copper shield
• Cable type: HF400 (flexible coaxial cable)
• Connector type: RP‑SMA male to RP‑SMA male
• Suitable frequency range: typical RF and wireless bands (consult device requirements)

How to use

Connect each RP‑SMA male connector to the corresponding RP‑SMA female socket on your devices, ensuring threads are engaged and hand‑tightened to provide secure mechanical and electrical contact. Route the cable so it is not sharply bent; maintain gentle curves to preserve the HF400 cable integrity and avoid kinking. When installing in a permanent setup, secure the cable with clips or cable ties placed away from the connector ends to prevent stress on the terminations.

Usage recommendations

For best RF performance, use the cable for applications that require a 50 Ω transmission line and avoid unnecessary extension with dissimilar cable types. Keep connector interfaces clean and dry; if repeated connections are expected, inspect connectors for wear. When measuring insertion loss or performing sensitive tests, minimize cable length where practical and maintain consistent grounding and shielding practices.
