ABSTRACT:
This invention relates to rotatable antenna feed polarizers for use in communication antenna systems, and seeks to provide, at economic cost, an antenna feed polarizer which is capable of being rotated accurately.
The polarizer is rotated by a threaded member rotated by a motor. A drive member is moved longitudinally by the rotation of the threaded member. Two flexible connectors are each attached at one end to the drive member, pass around idler wheels, are wrapped partly around the polarizer, and are fixed to the latter. Movement of the drive member pulls one of the flexible connectors and thereby rotates the polarizer.
Backlash is minimal because it occurs between only two moving parts, the drive member and the elongate member, and is achieved without using gears with minimum backlash, which may be expensive.
