Abstract (en)
The antenna (1) foresees a receiver (3) that on line (4) transmits to an alignment device (5) the signal coming from the satellite. With the antenna (1) in horizontal position, corresponding to the stand-by position, the lighting of the button on the driving unit (6) starts the signal search. On the receiver (3) the wanted television or radio chanel is selected through a remot control or on keyboard. The antenna (1) puts on an initial inclination of about 25 DEG and it begins a rotation of 360 DEG . If no signal coming from the wanted satellite is picked up, the alignment device (5) ends the rotation and it increases the inclination of 1,5 DEG . So in continuation till to align the antenna to the satellite and so having a perfect interception of the signal. <IMAGE>
