Ultra high frequency (UHF) is the ITU designation [1] [2] for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter).
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is at the top end of the ultra high frequency (UHF) band, at the lower end of the microwave range.
UHF broadcasting was used outside Kuala Lumpur and the Klang Valley by private TV station TV3 in the late 1980s, with the government stations only transmitting in VHF (Bands 1 and 3) and the 450 MHz range being occupied by the ATUR cellular phone service operated by Telekom Malaysia. The ATUR service ceased operation in the late 1990s, freeing ...
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
The 23 centimeter, 1200 MHz or 1.2 GHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between 1240 MHz and 1300 MHz.
Sources differ on the exact frequency range of the band. For example, the Swiss Federal Office of Communications, [1] the Broadcast engineer's reference book [2] and Ericsson India Ltd [3] all define the range of Band IV from 470 to 582 MHz. An EICTA paper [4] defines the range as 474 to 602 MHz, whilst the BBC define the range as 470 to 614 ...
Non-directional beacons (NDB)s operate on low frequency and medium frequency bands 190–415 kHz and 510–535 kHz. The instrument landing system (ILS) glide path operates in the UHF range of 329.3–335.0 MHz with marker beacons at 75 MHz. Distance measuring equipment (DME) also uses UHF from 962 to 1150 MHz. [2]
