A slip joint polarizer including a stationary waveguide (35) rotatably connected to a moveable waveguide (20), e.g. an ortho mode transducer, by a mating interface (60a, 60b), such as a pair of rotatable mating flanges. The moveable waveguide (20) is rotatable with respect to the stationary waveguide (35) to adjust least one of receive and transmit polarity. A probe (50) extends axially in the moveable waveguide, passing through the mating interface (60a, 60b) and into the stationary waveguide (35). The probe (50) may be attached to the moveable waveguide (20) so that the two rotate simultaneously. Alternatively, the probe (50) rotates independent of the moveable waveguide (20) to adjust for transmit polarity. During installation, the moveable waveguide (20) 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. Drawing : 5 Sheets Total Pages: 16 (FIG. - 1)
