Does anyone know how to hook up a Dish Tailgater to a 2013 38' Tiffin Allegro Red motorhome? We have an on-board existing satellite system (Winegard) but we would like to use the Tailgater when we are unable to get a good satellite connection. Dish's receiver is currently hooked up to the existing system. The are two coax connections in our outside electrical compartment and there is a label that says cable tripod. We have tried both connections but are still unable to see the tailgater. Dish tech support no help because it is a motorhome and they only know how to hook it up directly to the receiver.
