FM Transmitter fault, less than 10cm range, where is the PCB contact?

I have recently taken apart my N8 to replace case and digitizer screen and now find when back together that the FM transmitter range is almost next to nothing.

Where is the FM Transmitter PCB contact/chip or how does it 'transmit' ie through phone case, endcap, etc.

Has the metal contact above the flash unit and just below the volume button (N8 Teardown, Step 17, below left index finger tip, but not the three strips just to the right) have anything do with the FM transmitter.
