Abstract

In some embodiments a manually repointable satellite antenna includes a fixed satellite antenna reflector dish, a mounting arm fixedly coupled to the fixed satellite antenna reflector dish in a fixed position relative to the fixed satellite antenna reflector dish, an antenna feed assembly, and a manually adjustable linkage operatively coupled to the antenna feed assembly and to the mounting arm.
