What Does UHF Mean?UHF (Ultra-High Frequency) is the International Telecommunication Union (ITU) designation for radio frequencies in the 300 MHz to 3 GHz range. These frequencies are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, two-way radios, cordless phones, and many other applications.
Radio waves with frequencies above the UHF band fall into the SHF (Super-High Frequency) or microwave frequency range. Lower frequency signals fall into the VHF (Very-High Frequency) range. UHF radio waves propagate mainly by line of sight (the signal travels in a straight line between transmitter and receiver), and they are blocked by hills and disrupted by large buildings.
The main advantage of UHF transmission is that because the size of reception antenna relates to the size of the radio wave, the UHF antenna is more compact and less conspicuous than those required for lower frequencies. The major disadvantage of UHF is that because broadcast range reduces as frequency increases, UHF has a much shorter broadcast range than VHF.
