ALIGNMENT TO SATELLITE
Prodelin recommends that the 3.8 meter Az/El mount be positioned to the
satellite orbital arc by a trained or experienced installer. The instructions in
section 5.1 are intended as an overview of the alignment procedure.
5.1
INITIAL ALIGNMENT
The 3.8 meter offset reflector contains a 22.62
o
elevation offset look angle.
Therefore, when the reflector aperture is perpendicular to the ground, the
antenna is actually looking 22.62
o
in elevation.
1.
Raise the antenna by turning the 2" nuts on the elevation rod assembly.
2.
After the correct elevation angle is set, rotate the antenna in azimuth by
loosening the 2” nut on top of the positioner and removing the 1” hardware (4
places) in the positioner plate, refer to figure 10.
3.
At this time rotate the antenna in azimuth by turning the 1" nuts located at the
azimuth adjustment tube. Rotate azimuth until a signal is reached.
4.
Peak the antenna by fine adjustments made in both the elevation and the
azimuth.
5.
Adjust polarization by rotating the feed assembly in its mounting bracket.
6.
Re-install the 1" hardware in the Az/El positioner (form step# 2) and tighten all
adjustment hardware securely.
