A radome for covering an open end of a reflector dish of a reflector antenna has a generally planar portion of twin-wall extruded polymer material dimensioned to cover the open end of the reflector dish. A periphery of the planar portion is provided with a plurality of slits, the slits defining a plurality of tabs. The tabs are dimensioned for folding around a rim of the reflector dish. The tabs may be retained in the folded position by, for example, a band clamp or directly coupling a portion of the tabs to the planar portion.
