I am a long time dish subscriber. I would like to Sling my dish signal to another location where Dish service is not offered. I'm told I need to install the Sling Adapter on my home box. What else do I need to get the signal to my non-smart tv in other location? I know I can do this with a laptop outputting video to the tv but that is awkward. Is this possible with a tablet/phone and with Roku or Chromecast or Airplay?
