PURPOSE: A platform of a parabola antenna for receiving satellite broadcasting is provided to fix firmly a reflecting plate after controlling an azimuth and an elevation by improving a structure of a bracket. CONSTITUTION: A platform of a parabola antenna for receiving satellite broadcasting includes a base(11), a support bar(8), a first bracket(12), a second bracket(18), and a braker(20). The base(11) is fixed to a building. The support bar(8) is fixed to the base(11). The first bracket(12) is combined with a front end of the support bar(8). A plurality of loading sections(13) are formed at both sides of a front side of the first bracket(12) in order to control an azimuth of a reflecting plate(1). The second bracket(18) is installed at the loading sections(13). The second bracket(18) is fixed by inserting a converter arm(3) into a through-hole(19). The reflecting plate(1) is fixed to the front side of the second bracket(18). The braker(20) is installed in the second bracket(18) to perform a braking operation by using a clamp(22) and a nut(23).
