What frequency range is referred to as UHF?

UHF stands for Ultra High Frequency. According to the standard International Telecommunication Union (ITU) spectrum designations, the UHF band encompasses frequencies ranging from 300 MHz to 3000 MHz (which is equivalent to 3 GHz). In amateur radio, the most commonly used UHF band is the 70-centimeter band (420-450 MHz). UHF signals are strictly line-of-sight and are highly effective for local communications, penetrating buildings better than lower frequencies. Distractors covering 30 to 300 MHz refer to the VHF (Very High Frequency) band, while ranges in the kHz spectrum belong to the Low and Medium frequency bands. Remembering that UHF frequencies are a step above VHF helps keep the 300-3000 MHz range distinct.
