    TDXL-SH100 BDS SHORT MESSAGE HELICAL MULTIPLE ANTENNA
    创始人2025-01-11

    TDXL-SH100 is a spiral external antenna designed for receiving BDS B1I, S-band satellite signals, and transmitting BDS L-band signals. The antenna unit offers high gain, excellent circular polarization, wide directional beam and excellent high and low elevation performance. 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 UAVs, tablets, handsets and other fields.

    1、The antenna employs a laminated design to mitigate the mutual interference between the B1I and L bands and ensure stable antenna performance.

    2、The antenna unit is designed using multi-feed and multi-arm technology, which ensures excellent circular polarization, a wide beam pattern, and superior low-elevation angle signal reception.

    3、Compact size and highly integrated design.

    4、With a multi-feed and multi-arm design that incorporates zero phase center technology, the antenna ensures the stability of the phase center.

    5、Can be flexible customized according to customer request.
