I'm constantly being asked by clients how to get local channels through streaming. While there are options on streaming local channels, you can in many cases get them the old fashioned way. While there are some places in our area around the Highland Lakes wedged between hills that do not get good signal, most of the area can get several digital channels free through the air.
Check out this article I ran across from this article from TechHive that not only explains all the different antenna options out there, but also has a video explaining how you can find out what channels you will be able to get!
