VHF and UHF TV ReceptionAnalog and digital TV signals can be broadcast over two different frequency ranges: VHF (Very High Frequency) and UHF (Ultra High Frequency).
Over 90% of digital stations currently broadcast in the UHF frequency band, that means you can receive them with a UHF antenna. If some of the local stations you want to receive are below channel 14, especially channels 2-6, you will need a VHF/UHF antenna.
It may be a little confusing because until the analog to digital transition (June 12, 2009, when the analog signals stop), the TV stations will be sending two signals for each station, one analog and one digital. For example, ABC in your area may be transmitting the analog signal on channel 2 in the VHF band; it may also be transmitting its digital signal on channel 39 in the UHF band. After the transition the TV station will only transmit digital signals on one of these channels. Most TV stations will choose to continue to use its original channel assignment.
