Tallysman HC977E Embedded Triple-Band Helical GNSS Antenna with L-Band

Description

Overview

Weighing only 12 g, the lightweight HC977E embedded triple-band helical GNSS antenna with L-Band 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 HC977E 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: HC977.
