<p>The present invention relates to an arrangement for the omnidirectional orientation of an antenna. The arrangement comprises a housing mounted on a fixed mast so that it can rotate around the axis of the latter, and an antenna support mounted on the housing so that it can rotate around an axis perpendicular to the mast. Two adjustments assemblies comprising a toothed ring integral with one of the elements of the said articulations and a worm engaged on the said toothed ring and mounted immovable in translation on the other element of each articulation, allow the antenna to be adjusted finely in elevation and in the azimuth. The arrangement also comprises locking means for locking each of the articulations. In the event of the deterioration of the adjustment arrangements associated with the fixing means, the effectiveness of the immobilization is not prejudiced.</p> |
