Abstract
An antenna comprising a reflector (20) connected to a motor drive (30), a primary radiator (30) for transceiving a radio beam at an operating frequency impinged on the reflector (20) is disclosed. A coarse alignment 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. The coarse alignment system (70; 270; 370; 470) comprising an auxiliary antenna (50) connected to the control device (60) for communicating with a further auxiliary antenna (10b), at a second frequency different from the operating frequency. A fine alignment system is also present for electronic adjustment of the radio beam. A control device controls the coarse alignment system and the fine alignment system.

An antenna comprising:
- a reflector connected to a motor drive a primary radiator for transceiving a radio beam at an operating frequency impinged on the reflector;
- a coarse alignment system comprising a motor drive connected to the reflector for driving at least one of the rotation and the tilting of the reflector (220a;
- 220b), the coarse alignment system comprising a first auxiliary antenna connected to a control device for communication with a second auxiliary antenna located at a second antenna, the communication being at a second frequency different from the operating frequency;
- a fine alignment system for electronic adjustment of the radio beam;
- the control device for controlling the coarse alignment system and the fine alignment system.
A method for aligning a first antenna and a second antenna, the first antenna having a first primary radiator and a first primary reflector, the second antenna having a second primary radiator and a second primary reflector, the method comprising:
- causing at least one of the first primary reflector and the second primary reflectors to be at least one of rotated or tilted using a motor drive and thus establishing a communications link with a second one of the first antenna or the second antenna, wherein an auxiliary communication link is established between a first auxiliary antenna of the first antenna and a second auxiliary antenna of the second antenna;
- and
- adjusting the communications link by electronically changing parameters of the radio beam along the communications link.
