How does antenna height affect the azimuthal radiation pattern of a horizontal dipole HF antenna at elevation angles higher than about 45 degrees?

Select	Answer
A	If the antenna is too high, the pattern becomes unpredictable
B	If the antenna is less than 1/2 wavelength high, the azimuthal pattern is almost omnidirectional
C	Antenna height has no effect on the pattern
D	If the antenna is less than 1/2 wavelength high, radiation off the ends of the wire is eliminated
