Rotator for antennas receiving transmissions from satellite.

摘要

The rotator for antennas receiving from satellite is substantially formed of a waveguide segment (10) of circular shape in cross-section, a cylindrical rod of ferrite (14) arranged within the waveguide segment along the longitudinal axis thereof and supported by small discs (17, 18) of a material having good mechanical and electrical characterstics, and an inductor (21) arranged outside the waveguide segment and connected to an electric power supply in order to cause the polarization rotation of the incoming signal in presence of the magnetic field generated along the waveguide axis.
