Coaxial cable Rangeful HF400 1 m RP‑SMA male to N female, full copper, 50 Ω

Rangeful HF400 coaxial cable, 1 m RP‑SMA male to N female, is a short RF interconnect designed for reliable signal transfer in antenna, router and professional radio setups. Constructed with full copper conductors and a 50 Ω characteristic impedance, this cable is intended for applications where low insertion loss and stable impedance matching are important. The cable's connectors — RP‑SMA male and N female — provide a compact connection at one end and a robust threaded interface at the other, making it suitable for both indoor equipment and bench test configurations.

Advantages

The full copper conductors ensure consistent conductivity and reduced resistive loss compared with plated alternatives, while the HF400 coaxial construction maintains characteristic impedance and minimizes signal reflections. The combination of an RP‑SMA male connector and an N female connector offers versatility for connecting small wireless devices to larger antennas or test instruments. Its 1 m length balances convenience and minimal attenuation for short interconnect runs.

Suitable for

• Connecting routers, access points or wireless modules with RP‑SMA interfaces to larger antennas with N-type ports
• Laboratory and bench testing where a short, low-loss coaxial link is required
• Professional radio installations and RF equipment interconnects with 50 Ω systems
• Temporary or permanent antenna feeders for measurement and troubleshooting

Key specifications

How to use

Inspect connectors and cable for visible damage before use. Hand-tighten the N female coupling nut onto the mating N male thread; do not overtighten with tools unless specified torque values are provided by the mating equipment manufacturer. Align the RP‑SMA male pin carefully with the corresponding RP‑SMA female jack and engage until secure. Route the cable to avoid sharp bends, kinks or crushing points that could degrade RF performance. For test setups, label each end to keep track of connections and minimize repeated disconnection where possible.

Usage recommendations

Use the cable for short-distance connections to preserve signal quality; avoid using it as a permanent outdoor feed unless protected from moisture and UV exposure. When integrating into sensitive measurement setups, allow for warm-up time of connected equipment and verify VSWR or insertion loss with suitable test instruments to ensure expected performance.
