Bart, an intelligent, educated, and knowledgeable engineer, and I have
been in email contact for years, so I have pondered much of what he
has said. His virtual "center tap to ground" is certainly a valid concept.

But I can demonstrate a 180 degree phase reversal in a helical coil
in free space so the capacitance to ground is not the complete answer
to what is happening. A real-world helical coil is made out of real-world
wire and possesses some of the characteristics of real-world wire including
the ability to change the phase of the current every 1/2 wavelength
whether over ground or in free space. Light exhibits the same
characteristic. Technically, RF is light, just not visible light.
