YES!!! I have done just that. I now have 3 Roku devices in my house and 3 TIVO OTAs. (Over The Air). The TIVOs will record over the air digital signals and do some streaming channels (Netflix, Hulu, and many more), just not Sling. I have used the Roku devices and Sling to replace the cable channels I watch and antennas in the attic to replace the local channels. I subscribed to the 300MB internet service, but you can get away with less. The Roku devices I bought seem to also do 4K SUHD very well.
