Installation Procedures
The back structure assembly attaches to the rear of the reflector. The back structure
provides stability for the reflector and maintains the parabolic accuracy of the dish. An
example of the assembled back structure is presented in Figure 33.

Before assembling the back structure, verify that the appropriate parts are present. The
following steps provide the procedure for the back structure assembly.
CAUTION: Reflector must remain on level supports positioned under center edge of
each reflector segment with diameter setting bands in place during assembly of back
structure. Once back structure is attached and all bolts tightened, reflector will be held in
its assembled shape. If back structure is added with reflector in distorted shape, back
structure will hold reflector in that shape. If standing or walking on reflector becomes
necessary, concentrate major portion of body weight towards center of reflector panel.
