Installation Procedures
Refer to Figure 42. Use tape measure to set rim of subreflector to required distance of
119.110 in (302.6 cm) measured from the top of first seam hardware to the aperture
plane of the subreflector using three subreflector adjustment studs.
Attach right angle viewing piece to theodolite. Move subreflector laterally to align the
subreflector so it is centered with the theodolite while set at vertical (0° 00’ 00”). A hole
is provided at the center of the subreflector to facilitate alignment.
Ensure subreflector is centered and set at required distance. Snug adjustment hardware
after centering and height adjustments are complete.
Check distance between subreflector aperture plane and first seam reflector hardware.
