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.
