Coaxial cable Rangeful RP‑SMA Male to RP‑SMA Female HF400 3 m 50 Ω full copper

Rangeful HF400 coaxial cable, 3 m length, with RP‑SMA male to RP‑SMA female terminations and 50 Ω impedance is designed for reliable indoor RF connections. The cable features a full copper conductor and an HF400-type dielectric and shielding construction that maintain consistent signal transfer between antennas, Wi‑Fi devices, routers and RF measurement equipment. A flexible outer jacket allows easy routing in confined spaces while the RP‑SMA mates provide a secure mechanical and electrical connection for typical wireless networking and RF test setups.

Advantages

The full copper conductor reduces insertion loss and improves conductivity compared with plated alternatives, which helps preserve signal strength across the 3 m run. The HF400 construction offers a balance of flexibility and shielding effectiveness suitable for indoor use. Standard RP‑SMA male and female terminations ensure compatibility with a wide range of consumer and test equipment while providing stable mechanical engagement. The 50 Ω impedance matches common RF devices to reduce reflections and maintain network performance.

Suitable for

• Connecting external antennas to Wi‑Fi routers, APs and modems
• RF test benches and laboratory measurement setups
• Extending antenna cables for access points and signal boosters
• Short runs between wireless modules and antenna connectors in indoor installations

Key specifications

• Cable type: HF400 coaxial
• Length: 3 m
• Impedance: 50 Ω
• Conductor: full copper (solid or stranded copper core)
• Connectors: RP‑SMA male to RP‑SMA female
• Outer jacket: flexible polymer suitable for indoor routing
• Typical use: RF signal transmission for antennas and wireless equipment

How to use

Verify that both devices accept RP‑SMA terminations and have the same 50 Ω impedance requirement. Align the RP‑SMA male and female connectors, engage the threaded coupling by hand, and tighten until finger‑snug—do not over‑torque. Route the 3 m cable to avoid sharp bends and compression; maintain gentle bend radii to preserve shielding and prevent micro‑bends that can increase loss. For test setups, position the cable to avoid contact with large metal surfaces that may affect measurements.

Usage recommendations

Use this cable for indoor connections where flexibility and standard RP‑SMA compatibility are required. Avoid outdoor exposure to UV and moisture unless an additional protective sleeve is applied. For critical high‑frequency measurements, keep cable lengths as short as practical and inspect connectors periodically for corrosion or wear.
