Cradle-typeradio assembly Figure 12 illustrates the cradle-type radio assembly. The main parts of the radio assembly are mounted on two circular brackets so they can be rotated, similar to the movement of a cradle, to set the polarization of the feed horn. The arrows in Figure 13 indicate how the radio assembly can be rotated

Horizontal shim in place
Vertical shim in place
5.Install the vertical shim and O-ringin the same location. Because of its shape and alignment pins on the transmit/receive isolation assembly TRIA, the vertical shim can only be installed in the position shown in Figure 24 upper right photo. Note the position of the alignment pins. Likewise, the horizontal shim can only be installed in one position
