We live in a remote area when in the U.S. and one satellite dish does it all - internet and TV connections, same deal on the RV (motorhome)
Works great from anywhere, very few problems except on rare occasions of really bad weather and then only a brief interruption.
As for watching whatever is on the screen, there's a switch to make a selection of a specific channel and there's an on and off switch that works great too. Books are a great alternative to TV and helps the mind to visualize without having something else do it for you. Just my proverbial two cents' worth. Cheers...
