Sling TV is what we have. Hulu is similar.
They are both internet based, not satellite. They use an internet connection to stream to your TV. (either through a smart tv or a amazon/roku device)
We have pretty decent internet out here, so it wouldn't go out unless the internet was down. you do need stable internet though. if you have a "charged by the data" internet like a verizon mifi...then sling/hulu wouldn't be for you.
Our internet is actually a "wisp" which bounces a signal from ground tower, to ground tower (rural area thing) so its not exactly the fastest, but its more than adequate to support sling.
