Great question so lets go move ahead to the original date of analog to digital- February 17, 2009. Some TV stations will be moving to a different channel in a special frequency band that may require you to get another type of antenna from the one you use now.

Here’s an example, some channels in the VHF band (Channels 2-13) may move to the UHF band (Channels 14-51) and vice versa. Getting VHF and UHF signals entail different types of antenna elements. Many antennas are designed as combo units and will receive both VHF and UHF signals.
