It actually has a coaxial cable plug-in so that you can use any OTA antenna with it.You should be able to use the digital antenna you mentioned in your question. That said, you can get a new, Smart 4k TV for around $300-$450, so I would go that route unless you are on an extremely tight budget. 4k, plus Roku is a much better option in my opinion. If nothing else, Roku isn't going anywhere.
