Yet they do not.

See Fig. 2: http://www.antiquewireless.org/otb/lodge1102.htm


Why?

A lot more has been learned since 1887.

Can you measure the static electricity?


Sure, with a static meter.

Yet another device that didn't exist in 1887.


You will transmit just fine if you have the ground/chassis/counterpoise.


It depends on the type of antenna.

If it is a dipole, yagi, log-periodic, sturba curtain, rhombic, parabolic,
helix, loop, cubical quad, on any of many, many more types of antennas
that have no place or need to connect a ground, it would not.


Each of them has the chassis.

So your claim is that it is sufficient to "have the chassis" and that
this chassis does not have to be connected to the earth?

What constitutes "the chassis"?
Do you have any minimum size for the chassis to be a chassis?
