2.2. REFLECTOR QUADRANT ORIENTATION
The series 1244 reflector quadrants are labeled #1, #2, #3 and #4. These
numbers may be found molded into the back of each quadrant at the inside
corner. 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 5 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 3.
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 4.
When assembling for the inverted position, the Back Frame (item 14) must be turned 180
degrees from its standard position prior to its mounting to the Az/El positioner – see Step 2.
Also
note
that the optional feed stabilization kit cannot be used when the reflector is used in the
inverted position.
