A movable mount 1 for supporting a radiation reflecting, receiving or transmitting device, comprises a base 4 and a mounting surface 2 on which the radiation reflecting, receiving or transmitting device is mountable. The mounting surface is selectively rotatable about first and second axes 9, 20 relative to the base. The mount further comprises a first input device 7, a second input device 15, and a bearing assembly connecting the mounting surface to the first and second input devices. The first input device is rotatable about the first axis which is fixed relative to the base, the first input device being operable to rotate the mounting surface about the first axis. The second input device is rotatable about the second axis which is fixed relative to the base, the second input device being operable to rotate the mounting surface about the second axis. The bearing assembly comprises first and second members 12, 13, arranged to be concentric and rotatable relative to each other about a third axis 14, where all three axes intersect a common point 'A' which is fixed relative to the base. Preferably, the mount is used with a solar radiation collector or reflector for tracking the sun. |
