ANTENNA ALIGNMENT

ELEVATION ALIGNMENT

To obtain elevation

value for your satellite,

refer to the elevation

value written on Page 2.

IMPORTANT: Loosen Elevation Locking Bolts,

located in curved slots, on both sides. Loosen

Pivot Bolts 1/2 turn on both sides of Az/EL

Skew Mount.

Turn Elevation Adjustment Bolt clockwise to

decrease elevation and counterclockwise

to increase elevation. Position the

Elevation Alignment Indicator with

the appropriate mark on the

housing at the desired elevation

reading. Scale is in 1 degree

increments.

This will be an approximate setting.

Optimum setting is achieved when

fine tuning.

AZIMUTH ALIGNMENT

Refer to the Azimuth value

determined on page 2.

Values in chart must be adjusted for

magnetic deviation for your location for

correct compass reading. Equally tighten

the four Azimuth Locking Bolts until snug,

and loosen 1/8 turn. This will allow

azimuth rotation with slight resistance

and prevent the AZ/EL from tilting on pole.

Rotate the Reflector and Az/El Mount,

pointing it to the compass reading for your

location and satellite. If desired signal is

not located, increase or decrease elevation

setting and repeat the azimuth sweep.

Tighten progressively (1/8 turn each) all

four Azimuth Locking Bolts. Repeat until

85-95 ft-lbs. torque is reached.

Fine Tuning

Snug tighten (4) Top Plate Locking Bolts.

Turn the Azimuth Fine Tune Nut clockwise

or counterclockwise for Azimuth fine tuning.

Use an Azimuth Signal Strength measuring

device to obtain the most accurate alignment and maximum antenna performance. Alternate between elevation and

azimuth fine tuning to reach maximum signal strength, until no improvement can be detected. Tighten and torque

all hardware.
