Zusammenfassung:	PRIMARY SOURCE WITH FREQUENCY RE-UTILIZATION A primary source for a space communications antenna requiring a higher mode coupler comprises more especially a horn with two types of evenly spaced alternate corrugations whose depth decreases, for each of the types, from the neck to the opening, followed by an orthomode junction of the quasi-optical filter type, followed by a higher mode coupler placed in series in the reception channel of the primary source.
