ultrahigh frequency

ultrahigh frequency
Frequencies of electromagnetic radiation between 300 and 3000 MHz, or of wavelengths between 100 and 10 cm. These frequencies are mainly used by military for air-to-air and air-to-ground voice communications on a line-of-sight basis. In some instances, this may go as low as 225 MHz and still be referred to as a UHF (ultra-high frequency). The UHF band also finds applications in the glide slope of the ILS (instrument landing system) and in international (1000 MHz) DME (distance-measuring equipment). Secondary surveillance radar also operates in the UHF band with the mode on 1030 MHz and the code on 1090 MHz.
