Do I need a special antenna to receive digital television (DTV) over-the-air?
With a good indoor or outdoor antenna, you will maximize your DTV reception. In general, dependable reception of DTV will require the same type of antenna that currently works to provide good quality reception of analog TV signals.
However, after June 12, 2009 some television stations will be moving to a different channel in a different frequency band that may require a different antenna type from the one you may now have. For example, some channels in the "VHF band" (Channels 2-13) may be moving to the "UHF band" (Channels 14-51) and vice versa. Receiving VHF and UHF signals require different antenna types, although some antennas are designed to receive both VHF and UHF signals.
