How can I get it to look for a UHF station

The type of TV you have should not affect your reception. You need to know if your antenna will tune in uhf. Some antennas pick up uhf ,some pick up vhf and some pick up both. Make sure your antenna is able to pick up uhf. Here is link about antennas. It tells what type you need and what channels you can pick up where you live. https://www.fcc.gov/consumers/guides/ant... You should do a channel scan using your current antenna. Here is a link for a U tube video that shows you how do a channel scan on your Samsung tv. https://m.youtube.com/watch?v=1dkaczuSCg... If you have any questions please make a comment. I hope this helps.
