HC871 Dual Band Helical Antenna

Description

Overview

The HC871 is a lightweight helical antenna covering the GPS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1 frequency bands, designed and crafted for precision positioning. Weighing 25 g, the lightweight HC871 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 HC871 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. The HC871 is protected by a robust, military-grade plastic enclosure with an integrated SMA connector for screw-on mounting that securely seals the unit with an O-ring, complying with IP67 standards. The enclosure also provides two threaded holes in the base for secure attachment of the unit.
