How far away from your house can you install an HDTV antenna? We live on a farm, and the house sits down in a valley area. Up towards the road is our barn, which is at an elevation 30-35 feet higher than the house. I have power there, and I have a coax that runs underground that I could use, plus a CAT6 OSP cable (both in PVC conduits). I’d like to install an omni-directional antenna there to improve my reception capabilities, but I don’t know whether this is feasible, given the barn is about 500-600 ft from the house.
The hardware is nice, even though it's a bit bigger than other similar devices. The remote is also quite good, acting as a minimal, Apple TV-like remote on one side with a mini keyboard on the other. The keyboard makes a huge difference, but doesn't feel like it makes the remote overly complicated. If I had one complaint, it's that the keyboard is a little hard to type on—especially because it requires you to hold down Alt or Shift to get numbers or capital letters, unlike similar keyboards you'd find on phones. It's just a little off-putting at first. But overall, the remote is really great.
One last point on what to watch: If you really want to pay only for what you want to watch and nothing else, don’t forget that iTunes, Amazon, Vudu, Fandango Now, Cinema Now, Google Play and others will gladly sell or rent you movies and episodes of TV series, to watch on your computer or TV. If you’re thinking of your various subscriptions as an analogue to cable, then think of this option as akin to the old-fashioned “pay per view.” The fees can add up if you watch a lot, but these vendors have some free videos, too.

If you don’t have or don’t like any of the options above, there are a few ways to turn your TV into a “Smart TV.” There are a number of ways to do this. In the next section, I’ll cover the subscription services available. Certain devices only work on certain equipment so I’ll cover a few of these combinations in the Streaming Devices section of the post.
Live sports is admittedly the Achilles heel of streaming video services. The enormous licensing payments that pro sports leagues generate from cable networks simply puts them beyond the reach of Internet TV, with its significantly smaller viewing audience. Certainly, if your day isn't complete without updates from ESPN and ESPN 2, cutting the cable cord isn't yet a feasible option. But the situation is not quite as dire as you may think. Remember, an antenna gets you free OTA broadcasts, so you can watch big events like the World Series, Super Bowl, NBA Finals, and the Olympics. Home market NFL games are still on free TV as well (though they are subject to blackout restrictions if the stadium doesn't sell out).
Basically, when you go to your xbox and select to view video, you can view video from the xbox’s hard drive (stuff you download from xbox live), or from one of the connected media servers. Playon would be one of the connected media servers (in addition to the built in media server in windows vista -which only has limited streaming capabilities). Does that make sense or did I just muddy the water even more?
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!
