I got tired of Comast BS and when I caught them lying about why you need a box (It wasn’t because the content was digital it was because they were scambling the signal on purpose so you need a box) I switched to Direct TV. When I called to cancel service I never forget the Customer ‘NO’ Service Agent saying: “You will be back.” I made up my mind right there come hell or high water Comcast was NEVER going to get another penny from me EVER!
Well Comcast removed their analogue frequencies so yeah, you would need a box now days.
