Pedestal

In radar, the pedestal is an assembly of the antenna array. It is sometimes called a turntable and is a device for supporting and positioning the antenna. Typically, the pedestal allows the azimuth and elevation angles of the antenna to be controlled separately or in a coordinated way to permit different methods of scanning to ensure complete scanning of the space with the antenna pattern.

In a pedestal of the radar there are the following assemblies, which are partly duplicated for redundancy reasons:
