'''Ultra High frequency''', often abriviated to UHF, refers to a region of the [[electromagnetic radiation]] that has a frequency between 300 and 3000 MHz.<ref>[https://www.britannica.com/technology/UHF Ulta high frequency] at Britannica.com</ref> It is used to carry [[television]] signals for for channels 14 to 83 as well as some types of aircraft and navigation system.<ref>[http://www.eurocontrol.int/services/uhf Uses of UHF] from eurocontrol.int, European Organisation for the Safety of Air Navigation</ref> As the [[wavelength]] for waves in the UHF band is so small, they can be used to create directional beams. Unlike [[Very hihg frequency|VHF]], they reflect only slightly off the [[ionosphere]].
