ES45T-R Reflector Assembly

ES45T-R-1 Back Structure

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.

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.
