Thanks! I am in Taipei now, will try to find these connectors today.Those are SWD coaxial switch connectors. You can plug into it using something like this: http://www.woken.com.tw/product_00100A1 ... _spec.html
Different manufacturers call this connector differently.
It works like a switch - if you plug into it, a path to the antenna will break and signal will go only to the connector.
With this connector usually, there is no need for soldering to hijack the signal through the connector.
