Abstract: The waveguide connector assembly includes a waveguide connector having a first end, a second end, and a body having an interior surface and an exterior surface, the waveguide connector being configured to receive a waveguide in a first orientation or a second orientation at the first end, the second orientation being a rotation of the waveguide from the first orientation by either 45 degrees or 90 degrees to change polarizations. The waveguide connector assembly includes a movable sleeve having a first end, a second end, a body, and an engaging surface, the movable sleeve being configured to slide axially along the exterior surface of the waveguide connector, the engaging surface being configured to prevent axial movement of the waveguide when the movable sleeve is in an engaged position.
