Band I

From Wikipedia, the free encyclopedia

Band I is the name of a radio frequency range within the very high frequency part of the electromagnetic spectrum.

Band I ranges from 47 to 88 MHz, and it is primarily used for radio and television broadcasting.

Channel spacings vary from country to country, with spacings of 6, 7 and 8 MHz being common.

[edit] Worldwide Usage

In the UK, Band I was originally used for monochrome 405-line television. However this system was discontinued in the mid 1980s. Some European countries still use Band I for higher definition colour television, although this is now being gradually phased out.

In the United States, use of the band for colour television broadcasts is still widespread.

[edit] North America

The band is subdivided into five channels for television broadcasting, each occupying 6 MHz (System M).
