Fine elevation
adjustment The fine elevation adjustment rod (shown in Figure 50) allows
you to make fine adjustments of the antenna elevation. Where
subsequent instructions call for fine adjustment of the antenna
elevation, fine-tune the elevation setting as follows:
1. Make sure the two elevation lockdown bolts are loose enough
to allow the reflector to move as indicated by the arrow in
Figure 50.
2. While watching the signal strength display, adjust the fine
elevation adjustment nuts (Figure 50) to achieve maximum
signal strength:
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.
3. When the signal is peaked, tighten the two elevation
lockdown bolts.
Receive pointing Receive pointing peaks the receive signal. You must peak the
signal even if the antenna is locked to it.
You use the installation software to check the signal strength.
Then you adjust the antenna to peak the signal. The installation
software shows numerical and graphic indications of signal
strength. Detailed instructions for these procedures are given in
the following sections.
