Note that the null off the back of any such vertically polarized
array will be very sensitive to re-radiation from other nearby
vertical conductors, like towers and transmitting verticals.
In many installations, it may not be practical to locate the
array far enough from these objects to achieve anywhere near
the advertised f/b ratio.
