Subreflector of 34-m-diameter paraboloidal radio-antenna reflector tilted and translated to compensate for gravitational distortions of antenna structure. Position and orientation of subreflector adjusted to focus with respect to phase center of radio-frequency feed horn and primary focus of computed paraboloid best fitting gravitationally distorted main paraboloidal reflector. Restores gain lost when antenna aimed at angle other than design optimum elevation.
