Nice thing about the Braun, is that it is completed self contained. On coaches with fancy ceilings, or full width air ducts, a normal bat wing with a crank/turning handle on the ceiling is not possible. The Braun can be placed anywhere on the roof and only one coax wire running inside is necessary. It raises, lowers, and rotates, from a control panel inside the coach.
