<!-- In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the [[wavelength]] of the radio waves used,<ref name="Stutzman" /> so parabolic antennas are used in the high frequency part of the [[radio spectrum]], at [[ultra high frequency|UHF]] and [[microwave]] ([[super high frequency|SHF]]) frequencies, at which the wavelengths are small enough that conveniently-sized reflectors can be used.
