TV

Conventional analog TV is divided into 3 frequency bands:

Low VHF channels 2, 3 and 4 covering 54 to 72 MHz and channels 5 and 6 covering 76 to 87.75 MHz
High VHF chennels 7 to 13 covering 174 to 216 Mhz
UHF channels 14 to 69 covering 470 - 806 MHz

The US is moving to digital TV transmissions and the current VHF TV band will be used for internet access. Digital will be in the 470 - 860 MHz band.
But there are a huge number of households that have cable TV service which uses the 54 to 10002 MHz band to support 166 channels so TV analog TV sets to support cable will be here for some time.
