PURPOSE: A parabola antenna is provided to consider the receiving efficiency by minimizing the receiving wave rectangular area and manufacture a firm parabola. CONSTITUTION: A parabola(1) is positioned in a support frame(2). A wave guide(5) is installed on one side of the support frame(2). The parabola(1) is divided to a central plate(11) and a peripheral plate(12). The central plate(1) is divided to two piece plates(11a,11b). A center catching device(6) of the parabola(1) and a mask supporting arm(22) is installed on the inner peripheral surface of the support frame(2). A mast(3) is fixed by inserting a wave guide(5). The middle portion and the lower portion of the mast(3) are fixed by using fixing plates(24a,24b,35).
