A:Answer TV Antenna worked for me, I got about 13 channels, quality was pretty good, not sure if it was 4K, maybe 720p with some pixelation. Different local stations will perform differently I would imagine. The firestick I believe is 1080p only, the Fire TV is 4k, which that plays great 4K content. If you have Netflix, the TV, being smart. Enables 4K content on Netflix, which there's quite a large selection and it looks great! As long as you internet bandwidth with support all that data streaming in 4K, your golden!
