G9B05
Answer: CHow does antenna height affect the azimuthal radiation pattern of a horizontal dipole HF antenna at elevation angles higher than about 45 degrees?
AIf the antenna is too high, the pattern becomes unpredictable
BAntenna height has no effect on the pattern
CIf the antenna is less than 1/2 wavelength high, the azimuthal pattern is almost omnidirectional
DIf the antenna is less than 1/2 wavelength high, radiation off the ends of the wire is eliminated
