Large spacecraft antennas - New geometric configuration design concepts
A 1971 NASA technical report by R. E. Oliver proposing geometric configurations for large spacecraft antennas, written for aerospace engineers designing reflector systems. The plates are line-drawn ray diagrams of parabolic and hyperbolic reflectors, dashed axes, labeled foci and angles, and arrowed ray paths — usable as schematic linework, arrow vocabulary, and technical annotation layouts.
