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.
