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. It has a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a variety of high-precision Unmanned Aerial Vehicle (UAV) applications. This antenna has a low current Low Noise Amplifier (LNA) that includes an integrated low-loss pre-filter to protect against harmonic interference from high amplitude signals, such as 700 MHz band LTE and other near in-band cellular signals.
The HC871 is ideal for L1/L2 RTK surveying systems, military & security and mission-critical GPS timing applications. It 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.
