      產品詳細介紹Product Introduction

      HC885SXF Multi-Constellation Dual-Band Antenna

      The patented HC885SXF helical antenna is designed for precision positioning, covering the GPS/QZSS-L1/L5, GLONASS-G1/G3, Galileo-E1/E5a/E5b, BeiDouB1/B2b/B2a, and NavIC-L5 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)], as well as L-Band correction services. Weighing only 32 g, the light and compact HC885SXF features the 2nd generation Tallysman precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a wide variety of applications, including unmanned aerial vehicles (UAVs). The miniaturized 2nd generational helical element is about 25% lighter and 20% (1 cm) shorter than the first generational helical, without compromising on performance such as peak gain at zenith, low roll-off, and bandwidth. 

      The HC885SXF features an industry-leading low current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter. eXtended Filtering was added to the helical antenna to mitigate new radio frequency bands that interfere with GNSS signals. For example, new LTE bands have been activated, and their signal or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS antennas that receive space-based L-band correction service signals (1539- 1559 MHz). Similarly, new LTE signals in Europe [Band 32 (1452- 1496 MHz)] and Japan [Bands 11 and 21 (1476– 1511 MHz)] have also affected GNSS signals. Lastly, the Inmarsat satellite communication uplink (1626.5- 1660.5 MHz), commonly used on maritime vessels, can also affect nearby GNSS antennas.

      Field tests have confirmed that Calian's custom XF technology mitigates the new (Europe and Japan) and existing LTE signals, enabling the XF antenna to produce clean and pure GNSS radio frequency data.

      Calian's 2nd generation housed helical antenna elements are protected by a robust military-grade IP67 plastic enclosure. The enclosure’s base provides two threaded inserts for secure attachment, as well as a rubber O-ring around the outer edge to seal the antenna base and its integrated male SMA connector.
