[QUOTE="squire, post: 26583, member: 176590"] Hi, I´m just about to install a new DiSEqC motor SG-2100 on top of the roof. Until now I rotate my dish manually by simply turning (rotating) the mast under the roof and fix it with screws. In the past this method had given me access to Astra 19°, Hotbird 13° and Sirius 5° however changing the satellite required some inconvenience adjustment work. Rotation was geographically plain b´cause the mast was strict vertical mounted. When I install the motor, the centerline of the dish will move on a bow due to the declination between mast and motor-axis. Obviously it should follow the bow of the satellites positions. My dish´s dia is 0.8 meter and the LNB position is off-centered (squint) Now this is my question: When I use the motor rotating on an off-vertical axis in order to follow the bow-line that describes the satellites position on the horizont, is it mandatory to use a dish with an LNB in its center instead of a squint? With other words: Do I have to buy a new dish with an LNB in its center, or can I use the existing one? Not to mention that I will set elevation angle and declination angle strictly in accordance with the calculation values. An answer would be highly appreciated. squire PS.
