ANTENNA POINTING
Note:
The 1.2 meter reflector contains a 22.6° elevation offset look angle.
Therefore, when the reflector aperture is perpendicular to the ground, the antenna
is actually looking 22.6° in elevation. The Elevation Scale located on the side of
the Az/El Positioner allows for this offset angle.
Note: The following alignment procedure is intended only as a general reference
guide for this antenna. For proper antenna performance, accurate
alignment is critical. Therefore, it is recommended that your own detailed
procedure be used or contact CPI Technical Support Department for
additional recommendations.
STEP 1:
BEFORE ADJUSTING ELEVATION, LOOSEN THE HARDWARE ON
BOTH SIDES OF THE POSITIONER (2 PLACES EACH SIDE). REFER
TO FIGURE 3-1 FOR LOCATION.
Adjust the Reflector up or down in elevation by turning the 5/16" Elevation
Adjust Bolt at the top of the Az/El Positioner until the desired elevation is
read on the side of the Positioner. See Figure 3-1.
Once adjusted, snug the hardware at the sides of the Positioner.
Note: The Az/El Positioner has a scale on each side of the elevation
bracket labeled "A" and "B" as shown below. For the Series 1122
antenna, the "B" scale should be used (left side of Az/El Positioner
when viewed from behind).
Note: This scale is used for nominal readings and is accurate to ±2
degrees.
Note: Elevation Adjust Bolt is for adjustment only, it is not intended
to be part of the structural integrity of the assembly, therefore
"tightening" the Elevation Adjust Bolt is not necessary.
