Abstract

This invention relates to the steering of telecommunication antennae, and particularly to the mountings therefor. These mountings are used for supporting an antenna to allow communications to be established with a geostationary satellite i.e., one which is stationary in relation to the earth. The invention provides that the structure associated with the antenna be mounted at three points on the steering mounting, and the latter rests on the ground. That one of these points which is situated at the apex of said structure is provided with a bi-directional joint which allows the antenna to pivot about an axis XX in azimuth and an axis YY in elevation: these axes lying orthogonally to one another in a plane perpendicular to the axis ZZ of the antenna. The bi-directional joint aforementioned is mounted to pivot on the base mounting about the axis ZZ of the antenna itself.

Dependent claims

A steering mounting for a telecommunication antenna used to track a geostationary satellite, said mounting comprising a recticulate rigidifying structure including a generally symmetrical frame having an apex support point, a reflector assembly secured to said rigidifying structure, and means for supporting said reticulate structure on the ground, said supporting means including means for supportingly engaging said reticulate structure at three points, one of said points being situated at the apex of said reticulate structure, said means for supportingly engaging said reticulate structure including bi-directional joint means at said apex for allowing the reticulate structure to pivot at the apex about an axis XX in azimuth and an axis YY in elevation, said axes lying orthogonally to one another in a plane perpendicular to the axis ZZ of symmetry of the reticulate structure, and means mounting said bi-directional joint means on said supporting means for pivotal movement thereon about the axis ZZ.
