<p>The fault signal is derived from direction signals radiated from a satellite. It serves as a criterion for the angular deviation of the beamed satellite from the antenna axis. To the supply horn of a conical horn radiator antenna is connected a circular wave guide in a cross-sectional plane orthogonal to the waveguide axis. The wave guide has four output coupling apertures, each two in diametral opposition connected in a wave guide branch via wave guide components. The wave-guide (1) has an aperiodically attenuating conical restriction for utilisation of an EO1 wave for the generation of the fault signal. The apertures are in the form of coupling slits and are provided in the region of a first maximum of a specific component of the form, stationary EO1 wave.</p> |
