WIFI Cable R-SMA Plug / R-SMA coupling InLine 40861 1m

The InLine WIFI Cable R-SMA Plug / R-SMA coupling (1 m) is a coaxial extension cable designed for connecting Wi‑Fi antennas and wireless devices with R‑SMA connectors. It provides a 1 metre connection length and comes in black, offering a reliable link for antenna placement and signal routing without adding active components.

Advantages

This cable uses R‑SMA plug and R‑SMA coupling connectors on the ends to ensure a secure, threaded connection that reduces signal loss at the interface. The 1 m length gives flexibility when positioning external antennas or connecting devices in confined spaces. The simple coaxial construction keeps signal integrity for typical Wi‑Fi frequencies while remaining easy to install and resistant to everyday handling.

Suitable for

• Extending or relocating Wi‑Fi antennas and external antennas
• Connecting routers, access points or wireless adapters with R‑SMA ports
• Short antenna extensions in home or small office setups

How to use

Align the R‑SMA plug with the R‑SMA port on the device or antenna and screw the connector gently until hand‑tight; avoid over‑torquing. For the coupling end, connect to the matching R‑SMA plug on the antenna or device in the same way. Route the cable to prevent sharp bends and avoid placing it under heavy objects to maintain performance.

Recommendations

Use this 1 m R‑SMA cable for short extensions only; for longer runs, choose cables specified for lower attenuation at Wi‑Fi frequencies. Keep connections dry and clean and check tightness periodically to ensure a stable RF connection.
