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 azimuth on page 45).

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.
