Abstract

A mechanical means for deploying one of two or more feed sources within a test range is presented. The feed source selected for testing is properly positioned for use within the range by rotating one of two or more arms to an upright and locked position. An arm may further include a rotatable antenna wheel with two or more feed sources thereon whereby a selected feed source is rotated into position via the antenna wheel. The antenna wheel includes a center body, feed sources attached to the center body and aligned along a rotational plane, and a shroud disposed about the center body and feed sources. The antenna wheel may include a cooling system for managing heat generated by the feed sources and electronics therefore. In preferred embodiments, the feed source changer is mounted within the range so that a selected feed source communicates an emitted beam onto a reflector which is redirected as a reflected beam toward a device under test. Concealment panel(s) may be positioned adjacent to the feed source changer to minimize electromagnetic reflections therefrom.
