i would, but as i wrote:
i didn’t made a photo about the soldered antenna cable to the pcb, and the unit is already mounted on his final location, which is not accessible for me.
but it is not hard to imagine 
just solder gnd to gnd and antenna core to the middle (smallest) pad.
the proper way would be to solder to the pcb something like this or this, but i didn’t had at hand at the moment. (it is the same connector used in laptops or mobile phones for wifi / gsm)
