on another hand, some reports of reports of reports, seem to mention 
that the antenna is fixed and steered by motors somehow.  The photos 
show the classical 'dishes'.

This kind of antenna does not work if situated in an automobile, while 
the automobile moves at typical speeds.  There is another kind of 
antenna which is necessary: flat and with 'beam-forming'.
