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).
| Channel | Frequency Range |
|---|---|
| 2 | 54-60 MHz |
| 3 | 60-66 MHz |
| 4 | 66-72 MHz |
| 5 | 76-82 MHz |
