      產品詳細介紹Product Introduction

      HC977EXF Embedded Triple-Band Helical Antenna + L-Band
       

      The patented HC977EXF embedded helical antenna is designed for precision positioning, covering the GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, Galileo-E1/E5a/E5b, BeiDou-B1/B2/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 8 g, the light and compact HC977EXF features a 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 HC977EXF features an industry-leading low current, lownoise amplifier (LNA) that includes an integrated low-loss prefilter to prevent harmonic interference from high-amplitude signals, such as 700 MHz band LTE and other nearby in-Band cellular signals.

      Tallysman provides an optional mounting ring for embedded helical antennas, which traps the outer edge of the antenaa circuit board to the host circuit board or to any flat surface. To facilitate a successful installation and optimum antenna performance, Tallysman also provides an Embedded Helical Antenna Installation Guide.
