How many times do you need to be told? NO IT IS NOT TRUE, Marconi may
have
been correct when he made the statement considering the equipment and
practices at the time, BUT he was not correct as a statement concerning
radio systems in general. Things move on. Your mobile phone has no earth
connection, satellites have no earth connection. Accept this and move
on.

Radio on the Moon has the "earth connection". The Moon is smaller than
the
Earth.
Do you think that "the earth" must be giant?

You are misinterpreting what is meant by an 'Earth Connection'. Marconi
was referring to a direct connection to the soil, either by means of an
earth stake or wires buried in the ground.

Marconi explained what the 'Earth Connection' is:

""By "connected to earth" I do not necessarily mean an ordinary metallic
connection as used for ordinary wire telegraphs.
The earth wire may have a condenser in series with it, or it may be
connected to what is really equivalent, a capacity area placed close to the
surface of the ground (Fig. 4).
It is now perfectly well known that a condenser, if large enough, does not
prevent the passage of high frequency oscillations, and therefore in these
cases the earth is for all practical purposes connected to the antennae."

Your mobile phone has earth connection, radio on satellites and planes
have earth connection because they are on the chassis. Accept this and
move on.

No they don't have an 'earth connection'. The chassis is not an 'Earth
Connection'. Anyway it is perfectly possible the build a radio without any
connection to a chassis whatso ever and use a balanced antenna that also
requires no chassis or earth connection.

Accept the fact that earth connections are NOT required.

Are you better than Marconi?
