    创始人2025-01-08

    HG-P-TX0359 is a BDS short message reception antenna designed with multi-arm helical technology, supporting the reception of BDS short message signals in the S-band. It could widely applicable in portable equipment, handheld terminals that require short message reception capabilities.

    1. Using multi-arm helical technique, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring error;

    2.  The antenna unit features high gain and minimal gain roll-off, which provides excellent effect on low elevation satellite signals reception, and ensures the normal reception in some severe obscured locations;

    3. The antenna is equipped with a dust-proof, waterproof and shock-resistant cover, providing protection for long-term outdoor deployment.
