Abstract
A slip joint polarizer including a stationary waveguide rotatably connected to a moveable waveguide, e.g. an ortho mode transducer, by a mating interface, such as a pair of rotatable mating flanges. The moveable waveguide is rotatable with respect to the stationary waveguide to adjust at least one of receive and transmit polarity. A probe extends axially in the moveable waveguide, passing through the mating interface and into the stationary waveguide. The probe may be attached to the moveable waveguide so that the two rotate simultaneously. Alternatively, the probe may rotate independent of the moveable waveguide to adjust for transmit polarity. During installation, the moveable waveguide is rotated with respect to the stationary waveguide in order to adjust receive and/or transmit polarity. Once properly adjusted, the rotatable mating flanges are locked together to prevent movement.
