Adjusting polarization
This section describes how to adjust the antenna’s polarization to
the value determined by the installation software. Later, when you
point the antenna, you fine-tune the polarization adjustment.
Figure 16 illustrates how you adjust polarization by rotating the
antenna.
Adjust polarization as follows:
1. Make sure you know the polarization value calculated by the
installation software.
2. Locate the polarization scale (see Figure 12 on page 15). The
0 value is at the top of the Az/El cap.
3. Turn the Az/El cap to the correct polarization value. Align the
mark on the top of the Az/El cap with the correct value on the
polarization scale.
Figure 12 on page 15 shows a setting of
positive 3 °. Each tick mark represents 2 °.
4. When the polarization is at the correct value, tighten the four
polarization nuts. As you tighten, make sure the polarization
remains at the correct value.
Later, when you point the antenna, you fine-tune the
polarization adjustment.
