VHF is 30-300MHz, while UHF is 300MHz-3GHz.

Analog TV frequencies are different from country to country, but they largely start from 45-50MHz to 225MHz (VHF), and then from 470MHz to 850MHz (UHF).

In the PAL system each channel occupies approx. 7-8MHz of spectrum. The luminance (monochrome) is transmitted as a VSB AM signal. The chrominance (color) is transmitted on a 4.43MHz subcarrier as a QAM signal. The total video signal has 5MHz of bandwidth. Sound is then transmitted on a 5.5MHz subcarrier as a WFM signal.
