not yet moved to mark 3 on the mast, return to step 1 (in
Adjusting azimuth) and adjust it again. Keep moving the
reflector a little at a time until you get a signal.
4. Keep moving the antenna reflector a little at a time until you
detect a signal or until you reach the limit to the right.
5. If there is no signal after the antenna reflector has been
moved from mark 2 to mark 3 (1-1/2 in.), there may be an
error. If there is no signal, perform the following quick
checks.
– Check the coaxial cable connections at the LNB, IDU, and
all the connections in between.
– Make sure there are no obstructions such as trees blocking
the signal.
– Make sure you recorded and properly set the azimuth,
elevation, and polarization values.
– Verify the azimuth setting by moving 15 ft in front of or
behind the antenna and taking another compass reading.
Metal near the compass, such as a car or even a belt buckle,
can give a false reading.
– Point the front of the antenna reflector to the left of the
estimated bearing to the satellite so the alignment mark on
the Az/El cap lines up with the right-most pencil mark you
made on the mast.
– Repeat the steps beginning with step 1 (in Adjusting
Peaking the signal
After the satellite 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.
5. When you have peaked the azimuth, tighten the three clamp
nuts on the canister completely.
