[Elecraft] EH Antenna Patent

Non mea culpa!

I wrote only the first "question" part . . .

Playing Socrates, I was inviting others to think about the matter and come
forward with the desired facts. And several did . . .

If everyone comes away with the firm understanding that a propagating
wavefront must comprise an E-field component and an H-field component in
space quadrature and time phase, moving with the speed of light and in a
direction indicated by the Poynting vector E x H, then the old Greek
philosopher should be happy.

Bob, I admire  your restraint in referring to the technical content of the
EH and CFA antenna "theory" as you did . . .

The Poynting vector is E x H (both exist for a propagating
electromagnetic wave.)

There appears to be a bit of gobbledy-gook in the E-H and CFA
"physics".
