This seems to be turning into the Kodi thread but here's a couple items of interest for over-the-air TV:
The over-the-air DVR. Some external tuners, maybe even some TVs for all I know, can record digital broadcasts. I have the Mediasonic HW180 and there's also the Ematic that can be had for about $30, plus a USB stick memory is needed. My box has some flaws, as you might expect at that cheapness: biggest thing is the pausable TV isn't really usable, you have to do a full record, and the volume is reduced in playback. Its program guide is flawed but far better than my TV's basically nothing. The tuner section is solid and it outputs HD.
I also have the cheap 150 mile rooftop antenna. Of course 150 miles is unlikely, but I'm getting over 50 with good signal quality. In fact, by picking up another city I get options not on cable at my location. These also can be had for as low as $30 and can be identified by "X" shaped support pieces (plastic) holding "U" shaped front elements, the price and features. It has a rotor that allows adjustment without additional wires, but there is no visual feedback and it often moves in random directions, I can usually make small adjustments by signal strength but occasionally get it turned all around which takes walking outside and looking at it and retrying about 10 times. Also it's so boosted it might not be good near strong signals.
I wanted to ask if anyone had tried fully cutting the cable, once you drop the TV-internet bundle the internet itself is a less good deal. Comcast says I'd save $4 to keep the same internet level w/o TV, and $50 a month just for economy is also fairly ridiculous. I see cell based internet for cheap, e.g. freedompop or part of a cell phone service, the data or the quality is limited but how much? Looks like HD video is out, constant data usage concerns on cheaper options, metroPCS has free data for internet radio but only with their preferred providers (not mine).
