I requested an audio/visual schematic from Jayco for my Designer which they sent. Hooked my DirecTV receiver up to the coax from the Sat In outside jack, hooked the television to the HDMI out on the receiver, hooked up the dish, aimed it and all worked great.
This was first done 11 years ago and since upgraded to a Genie receiver. Still works great every day and after 11 years of doing it, I can aim my dish in less time than it takes to set up the tripod. Actual aiming takes less than 5 minutes including final tweaking.
