Abstract (en)
[origin: EP1098393A2] The antenna includes a main reflector, in front of which, in the direction of incident radiation, a sub-reflector with a reflecting surface is rotatably arranged. The sub-reflector (2) comprises a cylindrical axis (23) that lies in the direction of a main axis (22) of the main reflector (1), the sub-reflector being rotatably mounted on the cylindrical axis so that it can rotate at high speeds of 1500 to 3500 rpm. The sub-reflector may be mounted in an vibration-free manner, and free from unbalance. An Independent claim is included for a method of manufacturing a reflector for a reflecting antenna.
