Told by Dish that Hopper can be used with Tailgater...

Same! I've never had any luck setting one up myself, but I have so many people who swear by them. To each their own, I guess.
I set up my tripod mounted 1000.4 dish as often as daily. It rarely takes more than 15 minutes including locating a clear view to either the eastern or western arc sats using a virtual reality phone app. I use a $50 meter I bought years ago for final aiming and tweaking.
