Ultra high frequency 特高频

(重定向自UHF)
Another antenna type common at UHF; a reflective array TV antenna consisting of two high-bandwidth
Walkie talkies which operate on the 446 MHz PMR(Professional Mobile Radio) band.  The 67 cm wavelength permits them to use very short
Corner reflector UHF-TV antenna from 1950s

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. 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) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is high enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.
