Go to your local Wal Mart and look at the Over The Area Antennas OTA.
There should be one for around $40 that will give you credits toward Sling and other services, so you will get the 8-25 OTA channels depending on your location and a month free of Sling and the other services.
I dropped Direct TV over two years ago for a combination of Amazon Prime, Netflix, Sling, Kodi and what I can get on a OTA antenna. On a per month basis that would be around $42 and give you a massive amount of content. There is so much online content available you will never miss having Cable, I have 4 kids and non of them have complained yet.
