TDXL-CABLS4001 BDS one-line car antenna

创始人2025-01-13

TDXL-CABLS4001 is an one-line antenna designed for receiving BD3 B3I, B2b, B1I and S-band satellite signals, as well as transmitting BD3 L-band signals. The antenna unit offers high gain, wide directional beam, and excellent high and low elevation performance. The RF circuit integrates low noise amplifier, power amplifier and other RF front-end circuits. The antenna with special craft makes it possible to resist extreme temperature fluctuation and corrosion, which can do outdoor work for a long time. The antenna is widely applied in ship-borne, vehicle-mounted and other fields.

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、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.

4、The receiving circuit is equipped with front cavity filter, which enhances the whole anti-jamming ability of antenna reception.
