VHF, or very high frequency, refers to radio frequency electromagnetic waves in the range 30 to 300 MHz. In the U.S., television stations broadcast channels 2 through 13 in the VHF range between 54.0 MHz and 216 MHz, with ranges 72.0 to 76.0 MHz and 88.0 to 174 MHz not utilized for TV broadcasting. Each channel has a frequency width of 6.00 MHz. The table below gives the lower and upper frequency of each channel.
