Gibberish and nonsense based on ancient crap.

Connect an RF source through a transformer with the secondary connected to
a dipole and hang it from a balloon; works fine and no ground or chassis.

Start thinking. The dipole is a very long wire. The electrons are emitted
from the ends only. The rest of the wire is the chassis.
The very short dipole  (0.05 wavelengh) should not work fine without ground.

All antennas are the same:

"In conventional ICP (or TCP) reactors, a rf power is inductively coupled to
an antenna placed outside a plasma vessel. Such an external coupling system
is known to have several disadvantages. In order to avoid these
disadvantages, a new internal coupling system has been developed in which a
bare metal antenna is directly immersed in a plasma, thus forming a full
metal reactor. This is accomplished by generating magnetic field lines
around an antenna conductor, which effectively suppress the electron loss at
the antenna and hence suppress the anomalous rise of plasma potential.
Magnetic fields near the antenna are formed by superposing a dc current on a
rf current along the antenna. This type of ICP enables rf discharges at
rather low pressures such as ?3×10-4 Torr due to the magnetron effect. Other
characteristics of internal metal antennas are also discussed".

"the electron loss" and "the anomalous rise of plasma potential." apply to
all antennas.

no they don't. that discusses a rather unique situation of an antenna
in a very low pressure plasma. another case where google supplied
irrelevant information because of your ignorance of the actual physics
involved.
