[QUOTE="Channel Hopper, post: 1032706, member: 175144"] The range of such a mount will be determined by the distances of the two bearings from the central polar turning point and the length of the actuator arm. Basically the longer of each the better, the number of counts per degree improves and there is less stress on the motor gearbox and the bearings. There are caveats though, you need a larger space behind the dish, and the tracking speed between satellites will slow accordingly . Personally I would consider the polarmount from IRTE in the 90's/00's to be about the best available. Very heavy galvanised parts, adaptable and virtually unbreakable, but the disadvantage is a fixed diameter post of approximately 110/115 mm.
