      產品詳細介紹Product Introduction

      HC771E Single-Band Helical Antenna

      The lightweight patented HC771E embedded helical antenna is designed and crafted for precision positioning and covers the GPS/QZSS-L1, GLONASS-G1, Galileo-E1, and BeiDou-B1 frequency bands, as well as SBAS (WAAS, EGNOS & MSAS).

      Weighing only 4 g, The light and compact HC771E 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 HC771E 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.

      Tallysman provides an optional embedded helical mounting ring, which traps the outer edge of the antenna circuit board to the host circuit board or to any flat surface. Tallysman also provides support for installation and integration of embedded helical antennas to enable the integrator to achieve a successful installation and obtain optimum antenna performance.
