Abstract : The results of a wind-tunnel investigation of the aerodynamic behavior of hyperboloidal antenna structures are presented. Due to the increasing use of such dishes in Cassegrain antenna systems, the information should provide a useful tool for designers of antennas. The study also reveals a close correlation between the behaviors of hyperboloids and paraboloids of equal depth-to-diameter ratios, which indicates that the vast amount of available data concerning the effect of wind on parabolic shells can be used, with confidence, to design hyperbolic shells. An extensive bibliography, which includes publications in the areas of wind profiles and distributions, wind-tunnel experimentation, and the structural behavior of shallow shells, is also included.
