Newbie says THANKS! And asks about LOCAST.org

Tablo is a piece of hardware, with which you can watch and record local OTA channels from your antenna. Locast is a free streaming service. You can watch Locast on your Amazon Fire TV or Roku device, if you are in one of the cities in which they currently broadcast. Generally, you’ll get about eight or ten locals on Locast, depending upon your city … and of course, you’ll not be able to record any of them.
