I've used some apps on Roku to watch Live News. Other than that I haven't been watching live TV. I'm usually on Hulu, Netflix or Amazon Prime. I have a flat indoor antenna from my old house, but I can only catch 1 channel (CBS) with it. I still want to try and hook up an outdoor antenna to an existing old direct TV dish/mount at the back of my house. The wire is already hooked up to the house so technically it should work. I may try a better indoor antenna first though. Just haven't made it a priority. All I want is the basic channels (ABC, CBS, FOX, NBC). Anything else would be a bonus.
I may consider giving Sling TV a shot, but it's mostly for my wife. I rarely watch TV and watching sports less and less over the past several years. I do miss UFC Fight Nights on FS1 and UFC on Fox though.
