Hello, looking to pick some brains. I'm currently using a digital antenna inside the house, connected via coax to a 1080p 55" TV. Cutting the cable was the best thing that I could have ever done. Now I'm looking to upgrade to a 65" 4K TV. Since all TVs these days pretty much have just HDMI ports, is there a 4K antenna out there that connects via HDMI rather than coax? I've been told that coax wont carry a full 4k signal, so I'm trying to avoid a converter box.
