      產品詳細介紹Product Introduction

      HC871SXF eXtended-Filter (XF) Dual-Band Helical Antenna

       

      The patented HC871SXF helical antenna is designed for precision positioning, covering the GPS/QZSS-L1/L2, GLONASS-G1/G2, Galileo-E1, and BeiDou-B1 frequency bands, including the satellite-based augmentation system (SBAS) available in the region of operation [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].

      Calian's eXtended Filter (XF) antenna technology has been designed to mitigate out-of-band signals and prevent GNSS antenna saturation. The radio frequency spectrum has become more congested as new LTE bands are activated and their signals or harmonic frequencies [e.g. 800MHz x 2 = 1600MHz (GLONASS-G1)] can affect GNSS antennas and receivers. In North America, planned Ligado signals at 1525- 1536 MHz can especially impact GNSS antennas that support space-based L-band correction services (1539- 1559 MHz). New LTE signals in Europe [Band 32 (14521496 MHz)] and Japan [Bands 11 and 21 (1476– 1511 MHz)] have also been observed to interfere with GNSS signals. In addition, Inmarsat satellite communication (uplink: 1626.5- 1660.5 MHz) can also affect GNSS signals. Calian's custom XF filtering mitigates all existing signals and new Ligado and LTE signals, enabling the antennas and attached GNSS receivers to perform optimally.

      Weighing only 23 g, the light and compact HC871SXF features a precisiontuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a variety of applications, including uncrewed aerial vehicles (UAVs).

      All Tallysman housed helical antenna elements are protected by a robust military-grade IP67-compliant plastic enclosure. The enclosure’s base provides two threaded inserts for secure attachment, as well as a rubber Oring around the outer edge to seal the antenna base and its integrated male SMA connector.
