InLine WIFI Cable R-SMA Plug / R-SMA coupling 20m

The InLine WIFI Cable R-SMA Plug / R-SMA coupling 20m is a 20-metre coaxial extension cable equipped with an R-SMA male connector on one end and an R-SMA female coupling on the other. It is intended to extend antenna connections for WiFi equipment and related wireless devices while maintaining a stable signal over a longer distance.

Advantages

This 20 m InLine cable provides a straightforward way to extend antenna placement without changing device location, reducing the need for repositioning routers or access points. Constructed for durability, it minimises signal loss across its length and supports indoor and outdoor installations thanks to weather-resistant outer sheathing.

Suitable for

• Extending WiFi antenna connections for routers and access points
• Connecting external antennas to wireless repeaters or modem/routers
• Temporary or permanent antenna re-positioning in homes, offices, or outdoor sites

How to use

Connect the R-SMA plug to the antenna socket of your router, modem, or wireless device and attach the R-SMA coupling to the external antenna or antenna lead. Ensure connectors are tightened by hand — do not overtighten with tools — and route the cable along a secure path to avoid sharp bends or kinks. For outdoor routing, secure the cable with clips or ties and protect exposed connectors from moisture.

Recommendations

To maintain optimal signal quality, keep cable runs as direct as possible and avoid running parallel to power lines. If installed outdoors, seal exposed connector interfaces and check periodically for wear or damage. For installations requiring minimal signal loss over very long distances, consider using low-loss coaxial alternatives or professional-grade antenna cabling.
