An antenna comprising a reflector 20 connected to a motor drive 40, a primary radiator 30 for transceiving a radio beam at an operating frequency impinged on the reflector 20 is disclosed. A coarse aligmnent system comprising a motor drive is connected to the reflector 20 for driving at least one of the rotation and the tilting of the reflector, A fine alignment system 70 is also present for electronic adjustment of the radio beam such as adjustment of phase and/or amplitude. The coarse alignment system and the fine alignment systems are controlled by a control device 60. A method of aligning a first antenna and a second antenna is also disclosed. The antenna may be adapted to detect side lobes of the operating frequency for controlling alignment. The antenna may also comprise more than one radiating element. |
