Abstract: A window/seal and a satellite ground station antenna using the window/seal. A window/seal for a circular waveguide includes a right-circular cylindrical window having an axis, an annular rib surrounding and coaxial with the annular recess, and an annular recess between the cylindrical window and the annular rib. An outer diameter of the annular rib is configured to fit closely within an inside diameter of the circular waveguide.

Abstract: A mechanism to connect first and second circular waveguides. A first member includes two or more pins extending radially from a body, the first waveguide coaxial with the body and terminating at a first port at an end face of the body. A second member has a cavity coaxial with the second waveguide and configured to fit over the first member, the second waveguide terminating at a second port within the cavity. Slots disposed around a perimeter of the cavity engage the two or more pins. A cap fits over the second member, the cap including L-shaped slots to engage the two or more pins extending through the slots of the second connecting member. A wave spring between an inside surface of the cap and a shoulder of the second member urges the second port towards the first port when the cap is engaged with the two or more pins.
