InLine Wi-Fi Adapter Cable RP-SMA Socket to U.FL Plug 20 cm

The InLine WIFI Adapter Cable RP-SMA female to U.FL Plug 20cm is a short adapter cable that connects devices with an RP‑SMA female connector to equipment that uses a U.FL female socket, such as certain WLAN modules and router internal antenna ports. With a 20 cm length, it is intended for compact installations where a reliable RF connection between an external antenna or lead and a board-level U.FL interface is required.

Advantages

This adapter cable provides a direct, low-loss RF connection between RP‑SMA and U.FL interfaces and is compact for use inside enclosures. Its 20 cm length allows flexible routing in tight spaces while minimizing cable clutter. The InLine construction and standard connectors ensure compatibility with common WLAN devices and antenna types that use RP‑SMA and U.FL.

Suitable for

• Connecting an external RP‑SMA antenna to a device with a U.FL socket (for example, internal WLAN modules)
• Routing antenna signals inside routers, access points, or small enclosures
• Temporary or permanent internal cable connection between board-level RF ports and external antenna assemblies

Key specifications

How to use

Carefully align and plug the U.FL plug into the board-level U.FL female socket until it clicks into place without excessive force. Attach the RP‑SMA female end to the corresponding RP‑SMA male connector of the external antenna or extension cable, ensuring threads engage smoothly. Avoid bending the cable sharply near the connectors and secure routing inside the enclosure to prevent strain on the U.FL connection.

Recommendations

Use the adapter for internal or protected installations where the U.FL connector will not be repeatedly mated and unmated. For frequent external connections, consider using a bulkhead RP‑SMA connector or a longer, more robust pigtail to reduce wear on the U.FL socket.
