Abstract:
1. A pointing device for pointing a dish of a dish antenna in a desired pointing position, said dish having a rear side, a front side that in use is directed towards a remote receiver/sender according to a pointing axis, said dish antenna comprising a radome that has a domed portion with a predetermined diameter (R) such that said dish is contained within said radome in any pointing position of said dish, said pointing device comprising: an azimuth axis adjustment means, for rotation of said dish about an azimuth axis to adjust an azimuth angle formed between said pointing axis and a prefixed reference cardinal direction; an elevation axis adjustment means, for rotation of said dish about an elevation axis to adjust an elevation angle formed between said pointing axis and a predetermined line that lies on a plane defined by said pointing axis and by said azimuth axis; a tilt axis adjustment means, for rotation of said dish about a tilt axis, to adjust a tilt angle formed between a dish transverse axis and a support transverse axis of a support of said dish in such a way to compensate roll and pitch oscillatory motions; wherein said azimuth axis, said elevation axis and said tilt axis have respective distances from a reference point, such that during an adjusting motion by any of said adjustment means, said dish defines a portion of a space region that is contained within said radome, wherein said distances of the axes from the reference point are less than 30 millimeters, and wherein said reference point is located closer to said front side than to said rear side opposite to said front side, such that the distance between said dish and said radome is less than a determined distance S for any pointing position.
