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

not yet moved to mark 3 on the mast, return to step 1 in Adjusting azimuth and adjust it again. Keep moving the reflector a little at a time until you get a signal
Elevation
Fine-tunethe antenna elevation as follows
2.While watching the signal strength display, adjust the elevation adjustment nuts by turning them a few turns clockwise and counterclockwise until you peak the signal again
