The Very High Frequency (VHF) band is the segment of the television broadcast band covering channels 2 through 13. The Ultra High Frequency (UHF) band is the segment of the television broadcast band covering channels 14 through 83. Currently, the vast majority of TV stations broadcasting in digital are using UHF (14 and up) channels to do so. This is not due to any technical requirement of digital broadcasting, however. It is mostly because the UHF channels were more likely to be available in most markets. Eventually, after the digital transition is complete and TV stations no longer need to broadcast in analog, they may switch and use their current analog VHF channels for digital instead. You can buy antennas that receive UHF stations only or ones that receive both VHF and UHF.

UHF signals also require a lot more transmitter power to match the coverage of VHF stations, that's why the major stations all want to be in the VHF range.
