ABSTRACT:
An antenna exciter for two different frequency bands which consists of two polarization switches (3, 4) arranged axially one behind the other and of a feed horn (5). The polarization switches (3, 4) are circular tubes of different inside diameters, the diameters being the same over the entire length. To each polarization switch (3, 4) there can be connected, spaced axially from each other, two wave guides (6, 7, 8, 9) 90.degree. apart from each other. Opposite the wave guide (9) adjacent the feed horn (5) a stop closed by a short-circuit plate (12) is arranged in the corresponding polarization switch (4). Between the feed horn (5) and the adjacent wave guide (9) and between the points of connection of the two wave guides (8, 9) of the larger polarization switch (4), two axially extending webs lying diametrically opposite each other and of a predetermined dimension are arranged therein.
