Yes Roger, you are right and I agree.
I guess the CFA was an attempt to produce a "ready made"
flying far field already in the antenna structure.
G3JKV was right too. Please let us stop this discussion before
more internet bandwidth is wasted. Such a discussion will not
lead anywhere because of the laws of nature.
It was stupid of me to enter the thread. I apologize.

It is not essential to produce Both the E and H fields. Either one can
produce the other. For example the toroidal antenna launches only an E
field with an associated vector potential that produce, in the far field,
an H field to accompany the E field. Similarly a loop antenna launches
only an H field with its associated vector potential and as a result the E
field forms in the far field. In both cases one ends up with a complete
propagating electromagnetic field.
With respect, take a look at the curl of the vectors.
