Antenna alignment in 5 steps:

Step 1: To adjust polarization, loosen the two 1/4" bolts on the feed bracket and turn the feed/LNB assembly until the correct polarization setting is aligned with the alignment mark on the feed bracket. See figure 1. Tighten the two 1/4" bolts to 5 ft/lb. Polarization alignment

Step 2: Refer to the elevation scale located on the side of the Az/El positioner as shown in figure 2. To set the antenna system to the correct elevation angle, loosen the elevation pivot hardware on both sides of the mount just enough to unlock the lock washers. Then turn the elevation adjustment screw. Note: the scale has a 22.5° offset angle built in. Therefore, when the elevation angle is read on the scale, the 22.5° offset in the reflector has been accounted for.
Step 3: After making the cable connections to the LNB, rotate the antenna in azimuth to the correct azimuth heading using a compass to determine direction. Sweep the antenna slowly in azimuth until a signal is found. See figure 3.
Step 4: If the desired signal is not found, it may be necessary to alter the elevation angle slightly, and repeat the above procedure.
Step 5: Tighten all adjustment hardware on the Az/El Cap to 11 ft/lb.
