If you're one of the 10 people who still have a regular TV, you'll need to buy a digital converter box to watch TV in conjunction with your antenna, and once you get one, you will then get tons of crystal clear TV stations for free!  When we switched to watching Digital TV years back we instantly gained about 5-10 TV stations because some channels have the main channel, and then sub channels as well.

The Boxee Box is the most expensive device on the list at $175, and it's easy to see why. Unlike most of the others, the Boxee Box seems to be geared more toward the tech-savvy user, providing a more feature-filled media center without the hassle of building it and installing the software yourself. You can add all of your networked files (of nearly any file type) to a library that grabs thumbnails and plot information for a beautiful browsing experience, as well as stream content from services like Netflix and Vudu. If you buy it with the live TV adapter, you can also integrate your live TV-watching experience, which is pretty nice. Boxee also has a lot of social integration, letting you get recommendations from your friends on Facebook and Twitter and see what other people are watching. It has a browser, which—while a pain to use—can play many Flash videos not supported by one of its channels. It also supports AirPlay, which is wonderful to see in a non-Apple device.
There is NO WAY to get FREE CABLE TV over the air, with an HDTV antenna. It is not possible to get HGTV, The History Channel, AMC, CMT, TVLand, and those other types of channels over an HDTV antenna! I wish these websites and these phony ads would stop fooling people into buying these “magic sticks” and “magic TV” antennas claiming that they will be able to watch CNN, TNT, TBS, The Science Channel, Biography, National Geographic, etc. without paying a cable company. It is NOT TRUE. They can stream whatever with a subscription, but guess what? THEY STILL NEED TO PAY THE CABLE COMPANY FOR INTERNET ACCESS AND THAT COSTS ABOUT $80 A MONTH WHEN YOU CANCEL THE BUNDLES!
