Abstract
An antenna positioner is provided for use in an anechoic chamber to enable the radiation pattern of an antenna under test to be measured. A vertically disposed and selectively rotatable azimuth rotator pedestal is positioned in the anechoic chamber and a support is mounted on the pedestal for rotation therewith. A roll-axis shaft is mounted on the support for rotatably supporting the antenna under test. The roll-axis shaft rotator is positioned outside the anechoic chamber and has a horizontally disposed and horizontally movable connecting rod which is selectively movable into the chamber for connection to the roll-axis shaft to incrementally rotate the roll-axis shaft and the antenna under test.
