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.
