SOOOO this. This will tell you what you need, and will also help you aim what you get for the best signal.You can use this site to get the direction and distance of all OTA towers around you and what type of antenna you’d likely need to pick those signals up

The flat antennas with the metal backing grids arent TOTALLY directional, so you can split the difference, point the antenna between the two major sources, and pull them in at high angles OK.
