ABSTRACT OF THE DISCLOSURE The primary remote field radiator of a rotationally-symmetrical double reflection antenna, in particular a Cassegrain or Gregory antenna, being provided with a main reflector and a sub-reflector, is disposed behind the control opening of the main reflector, when viewed in the direction of the beam. This substantially shortens the connection between the primary remote field radiator and the transmitting - receiving devices. Moreover, the open- ing of the primary remote field radiator is substantially protected from rain and snow.
