Abstract

Design procedures are developed for determining Cassegrain-type antenna subreflector positioner strength and displacements under wind and gravity loading conditions. The procedures are applied to the JPL 70-m antenna subreflector design, and the resulting design details are presented. The generalized analysis can be adapted to other antenna and subreflector-positioners. The results show that the new design meets the strength and displacements criteria under worst-case loading.
