Title:
ANTENNA POSITIONER
Document Type and Number:
Japanese Patent JP2017146172
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna positioner that hardly affects the measurement of unnecessary radiation by itself.SOLUTION: The antenna positioner includes: a cylindrical cam fixing mechanism for stopping and fixing a rotation operation of a cylindrical cam; and a control unit for controlling a compressor and the cylindrical cam fixing mechanism. The control unit operates the compressor only during change of antenna polarization, and, during stop of the compressor, stops and fixes the rotation operation of the cylindrical cam by controlling the cylindrical cam fixing mechanism. Thus, the compressor can be stopped during measurement, and the antenna positioner hardly affects the measurement of unnecessary radiation by itself.SELECTED DRAWING: Figure 5
