As per the other responses, but I think your question is valid. Usually it's a bit like a sat dish that scans the sky to find whichever satellite it has been set to find. That's how Carpmart has set his system.
However, and I think this is what you're asking, how can it rotate and orientate if the dish is fixed flat to the roof after modifications made to it that involve removing the motor. The answer to that is that the 'window of vision' that the dishes have actually allow the dish to still receive a signal good enough to access even when only generally pointed in the approximate direction. Signal strength in these cases will be a lot lower but enough to be useable.
Whereas a sky dish needs to be pretty much in the perfect direction Flatty Mcflatface just needs an approximate direction. That's because they don't use one satellite, they use hundreds.
It's prob a lot more complicated than that but that's my understanding - which isn't probably technically correct !!
