    创始人2025-01-08

    TDXL-BLS4001 is a short message passive antenna that integrates BDS B1I, B2b, B3I, L and S bands, supporting BDS satellite system navigation signal transceiver. The antenna adopts multi-frequency band integration, transceiver integration, making it possible to connect with the BDS positioning short module board to realize the satellite communication. It is widely used in the navigation timing, track monitoring, measurement and control, military and other fields.

    1、 The antenna part adopts microstrip structure design, offering excellent Peak Gain and low elevation gain.

    2、 The antenna part adopts laminated structure, offering excellent isolation between the transceiver band signals.

    3、 The antenna is integrated with multi-band, and the signal is transmitted via coxial cable after merging, which is widely used.

    4、 The core components can be completely sealed with unique waterproof and dustproof design, making it possible to work normally outdoors for years.
