Examination of the radiation patterns of horizontal antennas confirms
that they invariably have zero response at zero elevation on their best
azimuths.

If this were true then most television broadcast stations would have nearly
zero field strength near the earth over much of their present coverage
areas.

Instead, the fields there are directly related to the peak ERP of the TV
station -- which typically is radiated in, or a few tenths of a degree below
the horizontal plane.
