Peaking the azimuth signal
Peaking describes the process of achieving the highest possible
signal strength available from the satellite. Once you have
detected a satellite signal, peak the signal as follows:
1. Mark the current azimuth bearing on the mast with a pencil
so that you can find it again later.
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 tilt 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.
