A surprisingly decent US government provided resource to check that: https://www.fcc.gov/media/engineering/dtvmaps

Edit: One thing to double check that surprised me is that the channel number these days doesn't reliably tell you if the channel is VHF or UHF. That is, a low-numbered channel like "3" or "8" could really be a UHF channel. I guess they let them keep long-established channel numbers for marketing purposes. So check what you really need before buying an antenna. The website above does provide the needed detail under "RF Channel".
