Abstract (en)
A C-shaped frame (22) rotatably mounted on a support structure (12), supports a hyperbolic sub reflector (20), a dual frequency dual circular polarization feed source (30) and a parabolic reflector (40) along source axis (A), and a planar reflector (50) along beam axis (B) perpendicular to the source axis. The stepper motors (24,52) rotate the frame along source and beam axes, respectively.
