Abstract
Abstract A polarized receiving apparatus in which there is provided a first waveguide for transmitting polarized signals and a second waveguide secured to the first for receiving polarized signals at one end thereof. An antenna means is provided having integrally formed portions including a receiver probe portion disposed in the second waveguide and extending generally axially of the second waveguide for receiving one polarization of the incident signal, a launch probe portion concentric with the axis of the first waveguide and extending generally axially of the first waveguide for launching said signal therein, and a drive portion intermediate the receiver and launch probe portions with said drive portion including a first gear. A drive source is supported in a housing member which defines the first waveguide and this drive source comprises at least a second gear adapted to mesh with the first gear for driving the antenna means.
