1000.4 Dish - Assembly, Pointing, and Peaking
2-8c
Fine-Tuning Elevation and Azimuth
1. Using the elevation rod, fine-tune the elevation angle to achieve maximum signal using the following sweep and
count method.
о
Using a 1/2” wrench, loosen the top elevation nut to allow the dish to be moved up and down in elevation.
о
Turn the bottom nut in one direction until the signal drops off the meter.
о
Reverse the direction of the wrench while counting the number of turns it takes to have the signal drop off in the
opposite direction.
о
Turn the adjuster back once again in the opposite direction by one-half the total number of turns to center the dish
on the signal beam.
2. Tighten the top elevation rod nut, and then tighten
the side elevation bolts. Reconfirm signal using
the push pull method after tightening all elevation
bolts.
3. With the signal meter still connected, using the
azimuth fine-tune cam, fine-tune the azimuth
angle to achieve maximum signal using the
following method.
о
First, loosen the three azimuth plate bolts
labeled with a ‘T’ just enough to allow the two
azimuth plates to rotate.
о
Using the 1/2” wrench slowly turn the cam
adjuster clockwise.
о
Watch the signal meter for value changes.
