External Antenna Connections, Wiring?

Hi,

Can someone please identify the two like U-fl connectors and also how I can wire an external antenna to this unit, it's not the Device identified by the Article. It's actually an Apple Airport Express 2012, the one that looks like a 3rd gen Apple TV but white. None of these antenna cables that go to RF-SMA connectors.

For the life of me, I cannot find an article anywhere on how to do it, regardless of how large the internet is. Someone here must know.

Thanks,

Chris

<- Need to know what these connections are, they look like U.FL but no U.FL connectors will attach to them? I need a way of adding external antennas to this Airport Express 2012. Thanks.
