4K Ultra HD Over the Air

Device needs constant restarts as the box shows very weak signal but other than that restart fixes the issue and we are good to go. There are also times when the box has voice delay with the picture ahead of sound. I get over 70 channels and I live out in the country with an antenna surrounded by trees and my closest station is about 30 miles. Box has a lot of little quirks but once they are figured out everything works. Yes it receives 4K programming which I have connected to a 2160P monitor. The box definitely needs internet connection as it is self reporting and has constant software updates to enhance it's operation. I run the Beta version of their software to get better features, it's worth it.
