I have made my own Yagi antenna and I would like to see if it works or not. I made the antenna based of these instructions: Easy to Build WIFI 2.4GHz Yagi Antenna
So I have soldered a coax cable to the pin 2 (the driven element). The center connector to one side and the shielding to the second side of the paperclip. But I have no idea how to actually connect it to my wifi dongle.. Does the center connector of the coax go to the "on board antenna" and then the shielding to the USB ground? also is the antenna the trace to the left of the dongle? The wifi dongle is an old Netgear w111v3. Any tips for me? Thanks!!
