I have a project that needs to be enclosed in an EMI-shielded aluminum enclosure. It looks like there's a uFl port on the Yun board, but I can't find any specs on it. Has anyone had any luck plugging in an external antenna into the board?
I'd like to plug a duck antenna (2.4GHz Duck Antenna RP-SMA - WRL-00145 - SparkFun Electronics), and I'm hoping to use SparkFun's interface cable (Interface Cable RP-SMA to U.FL - WRL-00662 - SparkFun Electronics).

Murata cable costs ~$50.00
Work around: disable internal wifi, connect USB wifi dongle. now USB cable is needed.
