3.Separate the end of the waveguide from the shim
4.Remove the horizontal shim and O-ring
Because of the shim’s alignment pins, you must rotate the TRIA 90 from its horizontal polarization position. You must rotate the TRIA before you re-attachthe waveguide end so you can insert the shim alignment pins into the waveguide end plate. See Figures 21 and
