eddie,
for a better understanding of transmissionline mode currents read the open sleeve antenna article in the arrl,
CEBIK also gives some clues in his "some j-poles that i have known" article,

the astroplane needs the mast or coax to form the transmissionline, its in the patent and won't work without it,
the relative conductor diameters / spacing and flare control impedance,

avanti claim the flare also controls takeoff angle as does mast length.
