Abstract: A vehicle, vessel or airplane having an antenna and a motor rotating the antenna, a rotation encoder outputting information relating to the rotation and outputting the information to two controllers of which one controls the motor. The other controller receives the rotation information and information relating to a position/direction/axis in relation to the vehicle/vessel/airplane and outputting a second signal based thereon. The output of the second controller may be used for controlling the motor to have the antenna directed toward e.g. a satellite irrespective of the motion of the vehicle/airplane/vessel.

Abstract: An antenna with a radiation emitter/receiver, a base and a mount system capable of rotating the radiation emitter/receiver in relation to the base around at least three axes, where a controller may ensure that the emitter/receiver is directed in a first direction in relation to the base while portions of the mount system rotate so as to prevent bearings of the mount system to deteriorate.

Abstract: A polarizer, such as a septum polarizer, which may alter between two states wherein, effectively, the septum is rotated 180 degrees around the longitudinal axis of the waveguide so that the polarization of the signals in the waveguide may easily be altered without having to alter receivers/transmitters connected to the waveguide.

Abstract: An assembly, a method of operating the assembly and antennas for use in the assembly, where two or more antennas (16, 18) each is adapted to output an output signal with one of two or more characteristics, only one antenna outputting a signal with a predetermined characteristic, such as a non-zero amplitude, whereby the output signals from the antennas may simply be added/summed while enabling selection of the signal with the predetermined characteristic using e.g. a simple filter.

Abstract: A dish-shaped element (10), such as a parabola, for use in an antenna for receiving and/or transmitting information, the element comprising a dish-shaped part (12) having a first side and a second side opposite to the first side as well as a first outer rim portion (12?) and a ring-shaped part (14) attached to the second side of the dish-shaped part, the ring-shaped part being attached to a predetermined area of the second side, the predetermined area extending from the first rim portion and no more than 25% of a distance, along the opposite side, from one point on the first rim portion to a second point on an opposite side of the first rim portion. The dish-shaped part may be forced into a desired shape while the ring-shaped part is glued thereto.

Abstract: A system for receiving information, the system comprising a receiver being configurable to receive signals within a plurality of first frequency bands and output a second signal relating to a signal received within a selected one of the first frequency bands, a processing element adapted to receive and process a third signal being within a predetermined, second frequency band, each first frequency band being wider in frequency than the second frequency band, and an intermediate element adapted to receive the second signal, generate the third signal by selecting, from the second signal, information with a frequency within the second frequency band, and output the third signal. Thus, in satellite communication, a 2 LO LNB may be made to appear as a 4 LO LNB seen from the Modem.
