ABSTRACT:
The antenna system for direct broadcasting satellite reception is formed by a parabolic reflector associated with source means, the reflector being positioned and held by means of a supporting foot formed by a hollow, tubular body fixed at its upper part to the rear central zone of the reflector and hinged at its lower part to a pedestal around a horizontal axis to define the elevation of the antenna. The pedestal includes a rotationally movable part to define the azimuth of the antenna. The tubular body of the pedestal supports a section sufficient to contain all the circuits associated with the antenna.
