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

Rangeful HF400 coaxial cable with RP‑SMA male to RP‑SMA male connectors is a 1 m, 50 Ω RF jumper intended for short runs between devices that use RP‑SMA ports. Constructed with full copper conductors and HF400 dielectric geometry, the cable is designed to provide consistent impedance, low insertion loss and stable signal transfer for antennas, routers, LTE/4G modules and laboratory test equipment.

Advantages

The full copper inner conductor and overall copper construction ensure good electrical conductivity and corrosion resistance compared with lower‑grade alloys. The 50 Ω impedance and HF400 design maintain impedance matching across typical cellular and Wi‑Fi bands, reducing reflections and signal degradation. RP‑SMA male to RP‑SMA male terminations provide a secure threaded connection while keeping connector gender compatible with devices that use reversed‑polarity SMA interfaces. The 1 m length offers flexibility for placement without excess slack.

Suitable for

• Connecting external antennas to routers and access points with RP‑SMA ports
• Linking LTE/4G modem modules or cellular gateways to antennas
• Short, low‑loss RF jumper runs in test benches and lab setups
• Replacing or extending antenna leads on wireless devices that require RP‑SMA male to RP‑SMA male connections

Key specifications

• Characteristic impedance: 50 Ω
• Length: 1 m
• Conductor material: full copper
• Connector type: RP‑SMA male to RP‑SMA male (threaded)
• Cable type: HF400 coaxial
• Intended use: RF signal transmission for cellular and Wi‑Fi frequency ranges

How to use

Align the RP‑SMA male connector threads with the corresponding RP‑SMA female port on each device and screw on gently until finger‑tight; avoid using pliers or excessive torque which can damage threads and alter impedance. Route the cable to minimize sharp bends and kinks — maintain gentle curves with bend radius appropriate for HF400‑type coax to preserve shielding and electrical characteristics. For test setups, secure the cable to prevent movement that could loosen connections during measurements.

Usage recommendations

For optimal performance, keep cable runs as short as practical and avoid coiling tightly around metal objects. Inspect connectors periodically for dirt or corrosion and clean with suitable contact cleaner if necessary. When connecting to equipment operating at higher transmit power levels, ensure all connections are firm and that the cable is rated for the intended frequency bands to prevent excess loss or heating.
