Peaking the signal 
(procedure)
After the satellite signal is detected, peak the signal as follows:
1. Mark the mast with a pencil so you can find the azimuth 
bearing again.
2. After detecting the satellite, continue turning the antenna 
reflector a small amount in the same direction you were 
turning it when you began receiving the satellite signal. 
Pause for 5 sec after each time you move the reflector. 
3. Turn the reflector in this fashion until the signal strength 
values displayed by the installation software begin to 
decrease. 
4. When the numbers begin to decrease, slowly turn the 
reflector in the opposite direction until you regain the highest 
number that was previously achieved.
(Achieving this maximum signal strength is called peaking 
the signal
.)
Make a note of the peaked signal strength for reference as 
you complete the pointing process.
5. When you have peaked the azimuth, snug down the three 
canister nuts as follows:
a. Alternately and incrementally tighten the lower two nuts 
until the flanges makes contact. 
b. Snug the top nut.
6. Fine tune the elevation adjustment to verify that signal 
strength remains at the highest level.
7. If necessary, fine tune the adjustments for azimuth, elevation, 
and polarization to make sure you have achieved and 
maintained the highest possible signal strength.
8. Erase all marks previously made on the mast.
9. Lock down (fully tighten) all adjustment nuts.
