I hope that you agree with me that monopole on the plane/satellite has
the
counterpoise in form of chassis.

You claimed that ANY transmitter with ANY antenna ALWAYS needs an
earth connection. That is incorrect. If Marconi claimed that,
Marconi was wrong.

Now you are more and more restricting the playing field by talking
about AM transmitters, monopoles, etc. And by extending your
definition of "an earth connection" to a chassis.

This of course leads to nothing. The original claim is still wrong.

The original Marconi's claim was:

In 1909 Marconi wrote:
