Product Introduction:
The RAT-830S is a compact, high-performance quadrifilar helix antenna designed for reliable multi-band GNSS signal reception. It supports GPS L1/L2/L5, GLONASS G1/G2, BeiDou B1/B2a/B2b/B3I, and Galileo E1/E5a/E5b frequencies, providing broad compatibility with major global satellite navigation constellations. Its RHCP design, 360-degree coverage, maximum 3 dB axial ratio, 28 dB active gain, and low 1.5 dB noise figure help maintain stable reception and positioning performance. With a wide 3.3–16 V supply range, low 13 mA power consumption, IP67 protection, and an operating temperature range of -40°C to +85°C, this multi-frequency GNSS antenna is engineered for dependable operation in demanding outdoor and industrial environments.
The RAT-830S quadrifilar helix GNSS antenna is well suited for applications requiring compact size, near-omnidirectional coverage, and consistent satellite tracking regardless of device orientation. Typical applications include UAVs and drones, unmanned vehicles, robotic platforms, high-precision surveying and mapping equipment, precision agriculture systems, fleet and asset tracking terminals, marine navigation devices, intelligent transportation systems, industrial IoT equipment, GNSS timing systems, and portable positioning devices. Its multi-constellation and multi-frequency capability makes it an excellent antenna solution for B2B navigation, tracking, telemetry, and precision positioning products.
