摘要：The invention relates to an antenna installation with an omni-directional antenna(M) and with an auxiliary antenna (A) the reception signals from which can be combined inrespect of amplitude and phase in such a way that a reception miniumu is produced in a

desired orientation in space. A further auxiliary antenna (A) is arranged and can becoupled in such a way that at least one reception minimum is produced where exactly onereception minimum points in the said desired direction in space and coincides with thesaid reception minimum produced by the first mentioned auxiliary antenna in respect ofits orientation and where the attenuations to the reception minimum produced by thefirst mentioned auxiliary antenna and to the reception minimum produced by at least oneof the further auxiliary antennae so that they do not of themselves inhibit the receptionof a transmitter sending at a predetermined minimum level, and that the receptionminima which coincide in their orientation jointly effect a greater attenuation so that theyare suitable for the suppression of jammers. A very narrow reception minimum isproduced. In other areas, satellite signals can be received.
