In these discussions, where the terms "VHF" and "UHF" come up, if the transmission has converted to DTV/HDTV, only the Channel Numbers are left. The Channels themselves are GONE, repurposed by FCC to other uses. Even the low numbers are actually on higher frequencies, and that's what the Wingman helps with. Say you liked "Channels 4 and 40." The 4 that displays on screen might now be on a higher frequency than 40. The tuner computer figures that out and shows you something you're familiar with. The bottom line? Something tuned for the new band, like Winegard WITH Wingman, a new Winegard model, or a Jack, will ALL help with EVERY broadcast TV channel.
