Az/El POSITIONER INSTALLATION
STEP 1:
3.2
REFLECTOR QUADRANT ORIENTATION
The 3.8M reflector quadrants can be assembled in either the standard or
inverted positions. The reflector quadrants are numbered 1, 2, 3 and 4. These
numbers can be found on the back of each quadrant embossed into the
fiberglass. Note that each quadrant has a longer side (major axis) and a shorter
side (minor axis). In the standard upright position, the antenna elevation angle
range is between 12 and 90 degrees. When viewed from behind in the standard
position (feed support at the bottom), quadrant #1 should be in the upper left; #2
is lower left; #3 is lower right and #4 in the upper right position. See Figure 4.
However, to allow a lower profile installation or in areas of high snow
accumulation, the reflector can be assembled in the inverted position (feed
support at the top). In this position, quadrant #1 would be in the lower right; #2
upper right; #3 in upper left and #4 in lower left position. See Figure 5.
Please note
that it is not recommended to invert systems with the Anti-Ice
feature. The inverted assembly would prohibit proper heating element location.
A) Lift the Az/El positioner assembly
(item 11) on top of the pedestal mast
so that it rests upon the slip flange.
B) Rotate the positioner assembly towards
the desired azimuth heading as shown.
C) Once the position is located, rotate the
positioner in either direction to the
nearest set of holes. The result is a
coarse azimuth setting (+/- 30 deg.).
The fine azimuth setting will be set
later.
D) Secure the positioner to the pedestal
with 3/4” hardware (items 15,16,17,18).
Tighten Securely.
