And after all that, the elevation pattern would be considerably
inferior to a dipole, as documented in the ARRL Antenna Handbook
in a graph illustrating the pseudo Brewster angle effects for
horizontal vs vertical polarization.  There is a reason why
you rarely see vertically polarized antennas on a tower, unless
ground wave propagation is involved.
