Adjust the elevation as follows:
Coarse elevation adjustment First set the elevation to a coarse setting:
1. Loosen the nut just below the elevation scale, and loosen the
nut on the opposite side of the elevation bracket. (See Figures
34 and 35.)
2. Adjust the elevation bracket until the elevation pointer
(Figure 35) points to the elevation angle specified by the
installation software.
Leave the nuts loose so you can fine-tune the elevation
adjustment.
Fine elevation adjustment
Fine-tune the antenna elevation as follows:
1. While watching the signal strength display to ensure that the
signal strength stays at maximum, adjust the elevation
adjustment nuts on the pointing tool (Figure 34):
a. Move the top nut to allow movement, then make
adjustments with the bottom nut.
b. Adjust by turning the bottom nut a few turns clockwise and
counterclockwise, until you peak the signal again.
2. When the signal is peaked, tighten the two coarse elevation
adjustment nuts.
3. Repeat both the coarse and fine adjustment steps to be sure
you have acquired the strongest possible signal.
