Adjusting the antenna
To point the antenna you make three adjustments to the position
of the antenna reflector:
• Elevation – Adjustment up and down
• Polarization – Rotational adjustment
• Azimuth – Side-to-side adjustment
These adjustments are illustrated in Figure 47. The corresponding
mechanical adjustments on the antenna are shown in Figure 48.
