A:AnswerIf you're wanting to connect an antenna to this TV, yes you can do it, just connect to the "ANT IN" coax connector. It's the same connector you would use for cable TV.
A:AnswerYes. I have connected to a flimsy indoor antenna, and I still get some of my local stations. I do get my local PBS channels with high quality, i.e. better quality than through U-Verse cable connection.
