The other interesting thing to consider is why a center loaded
antenna exhibits a current taper across the inductor whereas the
inductor in a base loaded antenna would not (I am assuming
here that the fact that a base loaded antenna produces significant
radiation is proof that there is minimimal current taper in the
base inductor)? And if the base inductor doesn't produce significant
taper, why does moving it to the center produce a taper. Also, if
there is significant taper in the center loaded antenna's inductor
then why does the portion of the antenna structure above the
loading coil produce any radiation?
BTW, I am not disputing Barry's observations. I am just trying to
reconcile them with theoretical principles. There seems to be a
disconnect.
Interesting discussion.

So, as part of your article I would expect (if I were a referee reviewing
your paper) that you would also remove the vertical radiator portions above
and below the coil, replace them with a parallel capacitor across the coil
and measure the current taper and the radiated field strength... If your
premise is that the EM field contained in an inductor is not as conserved as
previously thought, then a parallel tuned circuit, minus the radiating whip,
should result in radiation consistent with the observed current taper minus
heating losses... Correct?
