How does ROKU work? Does it use my internet connection to stream? Because I only have 160 GIGS per month.
ROKU requires an internet connection...
Get a good antenna for local channels (and there could be several dozen local channels - more than your cable or satellite provider were providing) - careful, not all antennas are created equal - some promise a lot but are junk. Then the Roku box to supplement.
I’m not sure how long it would take to use 160 gigs in a month, but yes, Roku does use the internet and the videos would play at hi definition. When you set it up, delete the apps it preloads as they are mostly pay for apps. Then load in PlutoTV, Crackle, YouTube (regular YouTube, not “YouTube TV”), TubiTV, STIRR, XUMO, Peacock, Redbox, Roku Channel, Baby Boomer TV, CBS Sports Stream, Weather Nation - all of those are free.
