1、The antenna part adopts symmetrical design to minimize the impact of the precision error and ensure the phase center stability.
2、The unit features an offset feed design, offering high gain, a wide directional beam, and excellent low-elevation signal reception, ensuring normal reception in special occasions where the signal is severely obscured.
3、Support BDS short message bidirectional communication. Support 1000 Chinese characters in single communication. Support BD3 regional short message: frequency point is L (uplink), S (downlink).
4、Transmitter circuit amplifier module is equipped with a power detection module, which can effectively reduce power consumption when not transmitting signals. Meanwhile, the final stage amplifier is equipped with charging protection circuit.
5、The receiving circuit is equipped with front cavity filter, which enhances the whole anti-jamming ability of antenna receiving.
