ANTENNA POINTING
The 1.2 meter reflector contains a 17.3° elevation offset look angle. Therefore,
when the reflector aperture is perpendicular to the ground, the antenna is actually
looking 17.3° in elevation. Refer to Figure 2.
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's Technical Support Department for
additional recommendations.
STEP 1:
BEFORE ADJUSTING ELEVATION LOOSEN THE HARDWARE ON
BOTH SIDES OF THE POSITIONER, REFER TO FIGURE 2 FOR
LOCATION. Adjust the reflector up or down in elevation by turning the 5/16"
Bolt at the az/el positioner until the desired elevation is read on the side of
the positioner. This scale is used for nominal readings and is accurate to
±2 degrees.
intended to be part of the structural integrity of the assembly,
tightening the elevation rod is not necessary. Snug the hardware at the
side of the positioner.
STEP 2:
Azimuth Adjustment: With the electronics set to acquire the satellite, rotate
the antenna in azimuth until the satellite is found. Tighten the canister
hardware at this time.
STEP 3:
Fine azimuth adjustment is achieved by loosening the three hex nuts
inside the Az/el positioner and the nut under the azimuth pivot then
turn the single hex bolt at the back of the positioner in either direction. Note:
Azimuth rod is for adjustment only, it is not intended to be part of the
structural integrity of the assembly, tightening the azimuth rod is not
necessary.
STEP 4:
Peak the antenna signal by fine adjustments made in both azimuth and
elevation until the optimum signal is achieved.
STEP 5:
Tighten all hardware used for adjustment.
