The reflector antenna contains a holder (1) on which the reflector (2) and the radiating element (4) are fitted. The holder (4) has a thickened point (16) in which radially running depressions of equal width are constructed. Inner end parts (18) of flat ribs (19), which project radially from the holder (1) and are covered by a grid (23), are located in these depressions. The inner end part (18) of the ribs (19) has an opening (34) in which the head (35) of a screw (32) is located. Adjacent to the opening (34) there is a slot (36) in the rib (19), in which slot (36) the bolt part (37) of the screw (32) is located. The tip of the bolt part (37) is screwed in the holder (1) so that the ribs (19) are removably attached to the holder (1). Such a reflector antenna can be dismantled and, in addition, can be produced in a modular system for various applications. This can be important, for example in the context of reception of satellite broadcast radio and television. <IMAGE>
