Ultra High Frequency refers to frequencies in the range between 300 MHz (i.e. above the VHF band) and 3000 MHz. In German, this frequency range is also known as Dezimeterwellen.


Broadcasting transmitters were never active in the UHF range. Some former UHF television channels are used today for DAB transmissions, but not in Switzerland.

In the upper UHF band, the television transmitters for analogue television in the UHF band used to be active. In the range between 471 and 863 MHz, the television channels 21 - 70 according to the CCIR standard are located; the channel spacing is 8 MHz, the audio carrier is about 5.5 MHz higher than the video carrier.

The successor technology DVB-T2 was never implemented in Switzerland.
