33-HC771E-28

## HC771E 

## Embedded Multi-Constellation Antenna 

Frequency Coverage: GPS L1 | GALILEO E1 | BEIDOU B1 | GLONASS G1 

## Overview 

The patented HC771E embedded helical antenna is designed for precision positioning, covering the GPS/QZSS-L1, GLONASS-G1, 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 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.
