Spherical radiation pattern

As I stand on the corner waving goodbye to that bus, I fondly recall
how the logic stood that no current could be found on the tips of
radiators, thus trim them off to no loss of radiation. It took very
few decades before Art had then recognized that his new antenna's tips
had no more current than the full-length one, and he trimmed that one
once again! New and improved (as the saying goes). Another decade
passed into the new millennium and he observed that he could extend
this logic once again to the point where his last design encompassed a
160M full sized antenna in the space of two shoe boxes. The TRIUMPH
OF TITANIC PROPORTIONS.
Is any simillarity between Art and Tesla?

"small" when compared with a wavelength. They were essentially a metallic
ball that was fed from the secondary of a resonant transformer. But they
appear to have had fairly large effective bandwidths in spite of their
electrically small size,"
