I sent this message two days ago and I did not see it arrive.

Although the subject is now out of context, I would like some comment on my question.

Hi Pieter-Tjerk,

If that is the case, and all the parts are at the same potential, how 
does a space craft, radio controlled model aeroplane

get their signals?

Surely every conductor in the unit will have a difference in potential 
due to being in a electromagnetic field.

Even in the legs of the FET. Although the potential will be extremely small.

Surely it is only necessary to have a change of the Vgs voltage of the FET.

So the geometry of the antenna has to be made to allow this to occur.
