摘要： A satellite network receiver connected to receive video and audio programs and commands from orbiting satellites through a steerable dish antenna. Commands are alternatively received by the satellite receiver via pager radio service or phone wire from a network controller that uplinked the satellite programming. All user controls are eliminated from the satellite receiver and the network controller uses its command capability to steer the users antenna and to analyze and initiate diagnostics performed on various parts of the satellite receiver.

摘要： Signal propagation apparatus is formed with a waveguide cavity for propagating first and second electromagnetic signals respectively having first and second electric fields that are distinguished outside the cavity by first and second polarizations, for example orthogonal polarizations, one vertical and one horizontal. Within the cavity, the electric field lines are curved and cross one another at angles that vary as a function of location within the cavity. A pair of probes are mounted within the cavity in spaced-apart relation to each other and have orientations that differ from the orientations of the electric fields outside the cavity. In order to send or transmit signals having electric fields that are respectively vertically and horizontally polarized, for example, thereby forming an angle of 90.degree. with respect to each other, the probes lie in planes forming a dihedral angle of about 80.degree.. This structure maximizes probe-to-probe isolation and cross-polarization nulls between the first and second electric fields.

摘要： An optimized feedhorn comprising a circular waveguide having a corrugated plate disposed around the outside of the aperture of the waveguide wherein the corrugations of the plate are capacitive as to E plane signals. The feedhorn includes a reduced aperture diameter which selectively protrudes beyond the plane of the corrugated plate. The amount of protrusion of the aperture is determined to approximately equalize E and H plane beamwidths and selectively shape the top and skirts of the signal pattern around the center frequency of interest.

摘要： A rotatable polarized signal receiver, having a rectangular waveguide orthogonally coupled to a circular waveguide, has a receiver probe portion oriented in the circular waveguide and a signal launch probe portion extending into the rectangular waveguide. A dielectric insert located in the circular waveguide transforms circularly polarized signals to linearly polarized signals. Since the receiver probe portion can be rotated right circular or left circular polarization can be selected and received.
