Digital Trends just did a story about this very topic. A few of them are Tivo DVRs, but there are other options too. I have no experience with any of them.Whatever you get, I want to hear about it. My wife wants to look into "cutting the cord".https://www.digitaltrends.com/home-theater/best-ota-receivers/
My wife wants to do the same thing. It's either an antenna / DVR combo ( some of those are cheap ) or streaming HDTV via a Roku over the internet. We are out in the hills where reception can be a problem.
I mounted a really strong antenea in the attic and wired it to my HDHomeruns in the basement. I got really good reception and its reliable. I use it every Sunday to watch football. It's also compatible with Plex.
What's a really strong antenna that you can attic mount?
