      產品詳細介紹Product Introduction

      HC976 Triple-band Helical Antenna with L-Band


      The patented HC976 helical antenna is designed for precision positioning, covering the GPS/QZSS-L1/L2, QZSS-L6, GLONASSG1/G2, Galileo-E1/E6, and BeiDou-B1/B3 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 42 g, the light and compact HC976 features a precisiontuned 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 HC976 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 IP69K-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.

      Mounting instructions available on our product page.
