Hi! I gave up using the embedded wifi interface with an external antenna... the cheapest (and working!) solution I found was to use an usb->wifi adapter with an RP-SMA dipole antenna (8 euros on ebay):

How about swapping the connector on board to a male one so that you can use the lead from any canibalised wifi router http://www.ebay.co.uk/itm/390611645159
From what I read about the Hornet AR9331 Wifi chip used on Yun, the two antenna inputs are set up for diversity (automatically selects which has the better signal strength). So unless you put an antenna with more gain than the onboard antenna, you will never see any change in the link quality (will continue to select the internal antenna). I have doubts that any of the monopole antennas you typically see will offer any improvement.
Thanks all for your help- I did get the external antenna connected, and it definitely, reliably, has boosted signal strength. I am getting good WiFi signal 150' from source. I used this cable to connect the antenna:
The connector is very tall an if you use a shield you will have to add male-female header pins between Yun and shield. Also there is an adapter between the cable and antenna:
Yes, about $60...expensive :o BUT for my application, it was the only way I could figure to get the range I needed- but like I said, it gets a strong signal 150' away from a standard wireless router.
As for the connection, it is solid. you press it down and it latches in place. the only drawback is that the connector here is tall, and if you are putting a shield on the Yun you need to have an addition set of male-female header pins to give the shield clearance.
