I don't know what we have. Haha. It's a digital antenna that we bought at Best buy and that's seriously all I know. We don't watch much over the air TV at all. We stream almost everything.I think past year playoff games did also stream on ESPN+...but not the regular season on cable.
Have you tried and amplified antenna, they are inexpensive on Amazon and over the air picture quality is so much better. I have one with 25 ft cord and run it to an upstairs window to get some channels. But still don't get them all.
