Quick question I do not seem to able to find an answer for. Is the OTA feature limited to antenna signals or will it also work with a cable signal (no cable box is required for my setup). It is cheaper to have basic cable bundled with my phone and Internet so since I have it, I may as well use it for times when the rain fade knocks my sat signal out. Before you ask why I have rain fade, I have a big oak tree partly blocking my dish that I do not plan to cut down. Thanks.
