Abstract
A method of beam switching a Cassegrain antenna used for radio astronomy by tilting the hyperbolic secondary reflector is described. The system described has been in use for over a year at the 11‐m millimeter wave antenna operated by the National Radio Astronomy Observatory at Kitt Peak, Arizona.Keywords
