    built-in BDS short message transmission antenna specification
    创始人2025-01-15

    TDXL-BSA503 is a built-in BDS short message transmission antenna, supporting the transmission of BDS short message signals in the L-band. It could widely applicable in portable equipment, handheld terminals that require short message transmission capabilities.

    1、Using multi-feed miniaturized design, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring error.

    2、The antenna unit offers high gain and minimal gain roll-off, providing excellent reception of low elevation satellite signals and guaranteeing a high success rate for signal transmission and reception at low elevation angles.
