Overview

The lightweight 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).

Features

  • Very low noise preamp: 2.0 dB
  • Axial ratio: ≤ 0.5 dB at zentih
  • LNA gain: 28 dB typ.
  • Low current: 15 mA typ.
  • ESD circuit protection: 15 kV
  • Invariant performance from 2.2 to 16 VDC
  • REACH, and RoHS compliant

Benefits

  • Extremely lightweight (10 g)
  • Ideal for L1 RTK surveying systems
  • Great multipath rejection
  • Increased system accuracy
  • Excellent signal-to-noise ratio

Details

Weighing only 10 g, the lightweight HC771E 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 HC771E features an industry-leading low current, low noise amplifier (LNA) that includes an integrated low-loss pre-filter to protect against harmonic interference from high amplitude interfering signals, such as 700 MHz band LTE and other near in-band cellular signals.

Tallysman’s provides an embedded helical antenna mounting ring that traps the outer edge of the circuit board to another 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.
