Before you go through setting up a satellite system try cellular data and online services.
Sling.com
HULU.com
and even Amazon Prime and Youtubetv, would be cheaper in most cases and if you are already using a smartphone, are very easy to try for free.
Sling and Hulu will both offer a free trial.
As far as getting the signal from your phone to your tv, if you decide you want to do this longer term Sling will give you a Roku device for streaming the data to your tv for no additional charge with a 3 month commitment to a $25 a month package. (or at least they did when I signed up)
