    创始人2025-01-14

    XXZDTXD-BW-TDXL BDS composite antenna is designed for receiving BD3 B3A, B1A satellite navigation and WiFi signals. Built-in low-noise amplifier with a two-stage filter offering excellent out-of-band rejection and strong anti-interference capability, ensuring normal operation in harsh electromagnetic environments. It meets high-precision measurement requirements and is suitable for applications with strict volume and weight constraints, such as handheld devices, tablets, UAVs, compact RTK and other portable equipment. The antenna also has built-in support for communication in the WiFi frequency band.

    1、Using multi-arm multi-feed zero phase center technique, the antenna enables the RHCP and phase center stability.

    2、Sophisticated low noise, high gain amplification and excellent out-of-band rejection.

    3、Compact size, lightweight, portable and easy to install.

    4、Integrated WiFi antenna, supporting short-range signal transmission.

    5、The antenna shell features waterproof and resistance in extreme temperature fluctuation, providing protection for the antenna's long-term outdoor operation.
