I have been able to install the tailgater on my 2011 Bounder Classic through the switchbox in the RV. I found these instructions on www.azrvsatellitetv.com
Look at the back for the Coax connected to it labeled "From Cable".
Remove it and attach it to the back of your Satellite Receiver labeled "Satellite In"
. Then take a short coax cable and go from "Out to TV"
on the receiver to back of the "Switched Box" where you removed the "from Cable"
Coax. Then, when you select Aux or Cable you willbe able to receive the signal from the Dish to the Receiver and then to your TV.
