A transportable weather radar, including radar electronics functionally located above the elevational joint, a frame superstructure rotationally connected to an elevational assembly supporting the elevational joint, a rotational drive assembly mounted below and supporting the elevational assembly, and at least one harmonic drive for positioning the radar antenna. The radar includes a fiber optic rotary joint positioned above a slip ring assembly which is positioned within a lower portion of the elevational assembly so that as the elevational assembly rotates a fiber optic cable connected to the lower end of the fiber optic rotary joint is stationary relative to the rotating elevational assembly. The slip ring assembly permits electrical signals to traverse through traditional metal cables from the pedestal to the frame superstructure where electronics are held. 1. A radar , comprising:a. a pedestal for supporting said radar;b. a rotational assembly supported by said pedestal, said rotational assembly including a harmonic drive actuator;c. an elevational assembly rotationally supported by said rotational assembly and including two axially aligned elevational joints mounted on opposite sides of said elevational assembly, and a fiber optic rotary joint mounted within said elevational assembly such that a fiber optic cable may pass down through said elevational assembly without rotational binding as it rotates on said rotational assembly;d. a frame superstructure rotationally supported by and spanning said elevational joints about said elevational assembly, said frame superstructure including a separate antenna mounting frame spanning said elevational assembly; and,e. a parabolic antenna assembly mounted on said antenna mounting frame having an orthomode feed horn and at least one waveguide assembly connected to said orthomode feed horn for bidirectional communications with a transceiver assembly.2. A radar as recited in claim 2 , further comprising a slip ring assembly ...
