Tallysman HC771E Embedded Single-Band Helical GNSS Antenna
The HC771E embedded single-band helical GNSS antenna supports coverage for GPS L1, GLONASS G1, Galileo E1 and BeiDou B1 frequency bands, as well as SBAS (WAAS, EGNOS & MSAS).
Description
Overview
Weighing only 10 g, the lightweight HC771E embedded single-band helical GNSS antenna 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.
A housed version is also available: HC771.
