We use the King Quest auto with Direct TV and the lock-in power injector/removal alarm unit. I've used it set up about 90 ft away and can't tell any difference from when it's roof mounted in an open CG.
I'm 70 years old, wear 2 hearing aids and trifocals, so HD/SD and stereo mean nothing anymore. Just give me a picture, a volume button and a Jack and Coke and I'm a happy camper! I do love my TVs!
It takes the King Quest anywhere from 3 to 10 min to lock on to the 101 and 119 satellites. It's the second thing I hook up next to the power.
