      產品詳細介紹Product Introduction

      HC871 Dual-Band Helical Antenna

      The patented HC871 helical antenna is designed and crafted 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)].

      Weighing only 24 g, the light and compact HC871 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).

      The HC871 features an industry-leading low current, low-noise amplifier (LNA) that includes an integrated low-loss pre-filter to prevent harmonic interference from high-amplitude signals, such as 700 MHz band LTE and other nearby in-Band cellular signals.

      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 O-ring around the outer edge to seal the antenna base and its integrated male SMA connector.

      Calian's helical family has passed a rigorous 30-hour vibration test procedure, consisting of five cycles of 2-hour tests per axis (x, y, z):

       • Cycle 1: 1.05 Grms;
       • Cycle 2: 1.20 Grms;
       • Cycle 3: 1.35 Grms;
       • Cycle 4: 3.67 Grms;
       • Cycle 5: 3.67 Grms.
