We just finished restoring a 1976 Airstream travel trailer and I have been thinking of my options for tv reception. I would like to be able to view live tv, and not just whatever I have loaded on a laptop/ipad etc. Until recently, I thought my only options were either an OTA antenna or a Dish Tailgater setup. What I just thought about however, may end up being cheaper - if I can figure out a way for it to work reliably. All of this would be done over a cellular network since most of the time wifi won't be available. If I purchased a Slingbox 350 (I already have the older model Slingbox Solo, but don't even know if it still works) and connect it to my Tivo at my house, can I then attach an Apple TV to my TV in the travel trailer and create a hotspot using my iphone and connect the Apple TV to the hotspot and then airplay from the Slingbox app on the iphone to my Apple TV?
