Yep as Dan said RG6 coax is the cable to use. I'm surprised your tailgater didn't come with a fifty foot cable. I thought they all did Hook the cable directly to the receiver and the receiver to one of the HDMI inputs on the TV. Turn on the TV and make sure the HDMI input is selected, then plug in the receiver and wait and follow the on screen instructions. Have your phone handy because if you are setting this up for the first time you will probably have to call dish. If everything works ok (finds satellites, downloads program guide), but then says unauthorized programming and to call dish. When you get a hold of a tech, tell them you need a hit and they will activate your receiver, but it will save you from having to walk through all the setup that you just did. Good, luck.
