The only reason we don’t is sports. We are sports fans, especially college football, and we rarely watch tv other than that. If I could get NFL, NCAA football and baseball, plus sports highlights ESPN style I’d pry the dish off the side of my house right now.
I get all the major channels including the local religious channels, PBS, and a bunch of retro channels. All major broadcast channels are required to have a substation which is retro TV programming, that won't change - even if some of the retro channels we have now get sold off, as one poster suggested might happen. Another one will pop up to replace it.
Occasionally with overcast skies, maybe one of the channels doesn't work, because of atmospheric interference. but the other channels will work.
