3.
Use the vernier scale to accurately set the elevation within 0.1°. See Figure 17. For example, to
set the elevation at 17.3°, align the “17” degree tick mark of the scale (seven tick marks past the
“10°”mark) with the “0” mark of the vernier. Continue to slowly raise the antenna until the “3”
tick mark on the vernier scale aligns with the next closest mark of the elevation scale. The
elevation is now set at 17.3° elevation.
4.
Use a compass to locate and line up the predetermined azimuth bearing.
5.
Loosen the eight canister set screws enough to allow the antenna to rotate about the mast pipe.
See Figure 18.
6.
Rotate the antenna in azimuth until pointed in the direction determined in step #4.
7.
Place a bubble level into the hole in the top of the AZ/EL assembly.
8.
Alternately tighten the eight canister set screws until all are tight and the bubble is in the center
circle of the level.
9.
Once level and all set screws are tight, tighten the jam nuts against the canister at each of the
eight locations.
