ABSTRACT:
A method for aligning a feed horn in an antenna system (100) is disclosed. The antenna system (100) includes at least one reflector surface and one or more feed horns (141, 142, . . . 145). The method includes the steps of determining a desired reflection point of the central ray from the feedhorn of the reflector surface, configuring a laser beam source to be mounted on the feed horn to enable a laser beam to travel substantially coincidently along the axis of transmission of the feed horn in a direction towards the reflector surface, and adjusting the azimuth and elevation of the feed horn to align the laser beam with the desired reflection point on the reflector surface. A laser aligning apparatus (200) for practising the above method and an antenna system aligned by means of the laser alignment apparatus (200) and/or method are also disclosed.
