Hi Andrew, I looked at the circuit schematics you kindly sent me, and it shows the only connections to the antenna amp are the coax connector and the antenna itself.
That seems to be what @ajsellors pic shows. That single wire at the top is the connection to the antenna itself (very similar to the heating element), I think, not an earth.
The current drawn by the screen heater is high, and requires a very good ground. The schematic shows this run from an earth point in the "C" pillar. As the @paolo_audi car has no diversity unit, I'm guessing it has only the one antenna.
