SMA TO IPEX1/IPEX4 RF CABLE, 15CM, WAVESHARE 21119

Waveshare SMA → IPEX1/IPEX4 RF Cable

The Waveshare 21119 RF cable bridges the gap between standard SMA connectors and mini IPEX1/IPEX4 (U.FL/MHF4) antenna sockets — making it an ideal accessory for mini WiFi modules, cellular HATs, or embedded wireless boards that require external antenna connections. This simple, reliable cable ensures secure connection and minimal signal loss, improving antenna performance and flexibility in enclosure designs.

Key Features:

• SMA male plug on one end and IPEX1 (U.FL) or IPEX4 connector on the other — perfect for attaching an external antenna to small wireless modules.

• Standard 50 Ω RF cable rated for low signal loss and stable impedance.

• Compact and flexible design suitable for tight or compact enclosures.

• Ideal accessory for 4G/3G/2G HATs, WiFi modules, LTE modems, and other RF devices with tiny IPEX ports.

• Helps optimize signal strength when using external high-gain or waterproof antennas.

Typical Use Cases:

• Connecting small cellular or WiFi modules with IPEX connectors to a high-gain SMA antenna placed outside a metal enclosure or vehicle.

• Upgrading signal reception for IoT devices, gateways, and embedded systems.

• Projects where antenna needs to be placed away from the main board for improved coverage or reduced interference.

• Compact embedded boards, Raspberry Pi HATs, routers, and modems where built-in antennas are insufficient.

The Waveshare 21119 RF cable is a practical, easy-to-use solution to extend and enhance wireless connectivity on miniaturized boards — giving you flexibility in antenna placement and improved signal performance for WiFi, LTE, cellular, or IoT applications.
