PURPOSE: A combination position detector/antenna is provided, in which a ball is arranged to move in accordance with coordinates formed at the metal surface of the parabolic reflector, to thereby detect coordinates of satellite in an easy and rapid manner. CONSTITUTION: A combination position detector/antenna comprises a feed antenna(11) for radiating or absorbing radio wave; a metal-plated parabolic reflector(12) having a focus portion where the feed antenna is positioned, and which reflects the radio wave radiated through the feed antenna so as to convert the radio wave into a parallel beam, and transmits thus-obtained parallel beam, or allows the radio wave to be focused to the feed antenna, wherein the metal-plated surface of the reflector has coordinates formed for detecting position of an object; a ball(14) disposed onto the metal-plated surface of the reflector, and which moves in vertical and horizontal directions according to the reflector moving to track the radio wave transmitted from the object and detects coordinates of the object; and a leg(15) arranged beneath the parabolic reflector, and which fixes the feed antenna and the parabolic reflector.
