Satellite antenna polarization switching mechanism

Abstract

This invention relates to a satellite antenna polarization switching mechanism, comprising a mounting bracket, a transceiver, a rotating base, a polarizer, and a positioning component. The transceiver is fixed on the mounting bracket, the rotating base is rotatably mounted on the transceiver, and the polarizer is fixed on the rotating base and can rotate together with the rotating base between a first polarization position and a second polarization position. The positioning component is located between the rotating base and the mounting bracket or the transceiver, and can position the rotating base relative to the transceiver when the rotating base rotates to the first or second polarization position. In this way, the polarizer can be quickly adjusted and the polarization direction can be switched by rotation, which is beneficial for the rapid deployment of satellite antennas in the field. Furthermore, the positioning component can stably position the rotating base to ensure that the polarizer is accurately positioned in the polarization position and avoid errors.
