Very high frequency

From Simple English Wikipedia, the free encyclopedia

Very high frequency (VHF) is an ITU label of radio frequencies.[1] The designation has all frequencies between 30 megahertz to 300 megahertz. Behind the VHF frequencies is called high frequency (HF). Above the VHF frequencies is called ultra high frequency (UHF).

In many parts of the world, VHF Band I was used for the broadcasting of analog television. Because of the worldwide switch to digital terrestrial television most countries ask that television in the VHF range uses digital encoding, rather than analog encoding.
