Abstract
Rear and forward reflector shells or dishes (36,38) are independently supported on a dynamically rigid truss structure (12) by means of separate studs extending from the forward nodes of the truss to the two shells. Forward node (22) carries adjustable rear shell stud (52) and independently carries adjustable forward shell stud (80). Both of the studs have flat portions oriented normal to the radius of the shell so that radial shell expansion due to temperature and temperature differential minimize shell distortion.
