The Rhombic antenna does not support your thesis.

On the contrary, I just whipped out an EZNEC rhombic
without taking any special care. I copied it out of
The ARRL Antenna Book, 20th edition, page 13-13.
I only installed ten zero ohm loads, but clicking
on "Load Dat" clearly shows the phase shift in the
traveling wave current along the wire.

Sorry, a rhombic won't run on the free demo version
of EZNEC.
