Question about Starlink Standard Kit

Hello We would like Starlink for our private property. I have the following questions: - With or without a motor? - Does the "dish" have to be accessible or can it also be installed on the roof so that you can no longer reach it? - If on the roof, which mount? Wall bracket or swivelling bracket? - Diameter of the pipe? - Is the Starlink cable longer than 15 metres? Many thanks and best regards Harry Welten
