Are DTV signals broadcast on special frequencies?
No. DTV broadcasts use exactly the same channels as regular analog television. While many DTV stations are now occupying UHF broadcast channels, broadcasters are allowed to move back to their original VHF or UHF TV channel once the transition to DTV is complete.The only caveat is that TV channels 51 through 69 will be auctioned off for other uses at the end of the transition to digital TV. Stations who originally had analog channels in this band will have to move, no matter what.One potential problem with re-using low VHF (2-6) TV channels for DTV is the possibility of interference from other signals during certain times of the year. “Skip” may bring in distant broadcasts on the same channel and create interference. Impulse noise is also a problem on low VHF channels. Whats more, the physical size of low VHF and high VHF antennas is much larger than that of a UHF antenna.

While many DTV stations are now occupying UHF broadcast channels, the plan is to allow many broadcasters to move back to their original VHF or UHF TV channel once the transition to DTV is complete. During and at the end of the transition, channels 51 through 69 would be auctioned off for other uses. One potential problem with re-using low VHF (2-6) and high VHF (7-13) TV channels for DTV is the possibility of interference from other signals during certain times of the year. Skip may bring in distant broadcasts on the same channel and create interference. The physical size of low VHF and high VHF antennas is much larger than that of a UHF antenna.

Tests so far seem to indicate that high VHF channels (7-13) are quite well suited for DTV broadcasts, and many br
