Abstract
A dual band signal receiver is provided with inner and outer relatively coaxial cylindrical waveguides electromagnetically coupled to respective upper and lower band rectangular waveguides and ports through suitable polarization switching probe assemblies. The rectangular waveguides are mounted adjacent one end of the outer cylindrical waveguide. The rotatable probe assembly of the inner cylindrical waveguide is electromagnetically coupled to the high band rectangular waveguide by a suitable transmission line extending substantially along the longitudinal axis or centerline of the outer cylindrical waveguide.
