The HC771 is a lightweight helical antenna covering GPS/QZSS L1, GLONASS G1, Galileo E1, and BeiDou B1 frequency bands, as well as SBAS (WAAS, EGNOS & MSAS).

Ideal for a wide variety of applications including Unmanned Aerial Vehicles (UAVs), the lightweight HC771 weighs only 24 g and features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane.

The HC771 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 HC771 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 three threaded holes in the base for secure attachment of the unit.

An embedded version is also available. Click here to learn about the HC771E.
