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.
