ABSTRACT OF THE DISCLOSURE: Device of the type capable of detecting distortions in a reflector, of producing an error signal controlled by the distortion detector and of correcting distortions in the reflector controlled by this error signal. The problem to be solved consists of making it possible to produce directly an error signal, regardless of the correction method utilized. The detector includes an HF signal transmitter located remotely and cooperating with the arrangement of feeds of the beam forming network which is in the receiving mode, and includes a central feed and some peripheral feeds in a symmetrical arrange- ment, and the error signal producer includes an adding circuit connected to two peripheral feeds. The invention is advantageously applied to antennas mounted on satellites.
