... believe me, many phd's have made their life studies of reducing
that last little bit of radiation off the side or back, and the conclusion
is??? you can't do it.

Just to note that an inline array of radiators spaced 1/2 wavelength apart
and fed with equal phase, but binomial power distribution produces a
radiation pattern with zero sidelobes, and an infinite front-back ratio.
These designs are shown in chapter 5 of Kraus' "Antennas for All
Applications," 3rd edition.

Such antenna arrays have been marketed by FM broadcast antenna OEMs to
reduce the power density (radhaz levels) on the ground around towers with
high power FM systems on them.
