A:Answer I would get hdhomerun to access local channels. We have the 4tuner because of various tv in various rooms. You will need a quality tv antenna. The best unit to get for your android tv , especially if your want to record and watch sports without choppy movement is to get Nvidia Sheild. If you don't care about recording. I use a lower cost Mibox3 in the living room. If you are really plugged into Amazon, you may want to consider an Amazon product. With the Nvidia I added an external hard drive to upload files or record. Also make sure your router and internet speed rock.
The HDhomerun takes care of access to the local channels, but we have signed up with PlayStation Vue for cable shows we like to watch. I would try the free trials, which is what I did for these services-PlayStation Vue, YouTube TV, Sling, etc. I choose PlayStation Vue because it has all the stations my family liked to watch and a lot of sports.
I am enjoying being a cord cutter. Make sure you consider that you have now made your tv act and look like your smart phone. You are now using apps to provide your viewing and also game playing, if your into that. I'm a girly nerd, so all this appeals to me. But others may not be into setting this up.
Hope this helps.
