    Circular aviation one-line antenna
    创始人2025-01-14

    TDXL-CA05D is an one-line antenna designed for receiving BDS B3I, S-band satellite signals, and transmitting BDS 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. The antenna is widely applied in aviation, aerospace, agriculture machines, container industry, telemetry 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、Iterated and upgraded from the traditional circular aviation antenna, maximizing the size and structure consistency.

    3、The outer cover adopts plastic material that can resist high temperature, and it is designed to protect internal circuit through thermal insulation.

    4、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.

    5、Transmitter circuit amplifier module is equipped with a power detection module, which can effectively reduce power consumption when not transmitting signals.
