I don't have a tailgater - I have a Winegard Pathway X2, but they work the same.
These receiver dishes are automatic, but they need to have a clear view of the satellites to start with. They also get their operating power through the cable. If you completely kill power to the inside receiver box (unplug it) or disconnect the cable, then it will have to go through the entire satellite acquisition process again.
How do you decide where to set the Tailgater ? They need to have a mostly unobstructed view. I use the DISHFORMYRV app for Iphones. $10. Works great.
