Well, this one usually goed more like "I read that in 1910 this result
was found in experiments, so everything we learned after that must
be completely wrong"...

I read that now:

""A further feature of the structure of negative coronas is that as the
electrons drift outwards, they encounter neutral molecules and,
withelectronegative molecules (such as oxygen and water vapor), combine to
produce negative ions. These negative ions are then attracted to the
positive uncurved electrode, completing the 'circuit'.". From: Negative
coronas. Mechanism.
http://en.wikipedia.org/wiki/Corona_...gative_coronas

""The difference, then, between positive and negative coronas, in the matter
of the generation of secondary electron avalanches, is that in a positive
corona they are generated by the gas surrounding the plasma region, the new
secondary electrons travelling inward, whereas in a negative corona they are
generated by the curved electrode itself, the new secondary electrons
travelling outward."

"in a negative corona the electrons are generated by the curved electrode
itself".

Is the field electron emission from the tip top of antenna or not?

Where you learned that no field electron emission?
