Ultra High frequency, often abriviated to UHF, refers to a region of the electromagnetic radiation that has a frequency between 300 and 3000 MHz.[1] It is used to carry television signals for for channels 14 to 83 as well as some types of aircraft and navigation system.[2] As the wavelength for waves in the UHF band is so small, they can be used to create directional beams. Unlike VHF, they reflect only slightly off the ionosphere.
