XF GPS L1/L5 / GAL E1/E5AB / BDS Helical Coaxial (HC) Antennas   The Calian quadrifilar HC technology features a precision-tuned helix antenna element that delivers excellent gain and axial ratio from zenith to horizon and over all azimuth angles to help minimize multipath. Designed for precision positioning, these antennas combine low power low-noise amplifiers (LNA) with an integrated low-loss pre-filter to protect against out-of-band interference. With extremely low weight and strong performance without a ground plane, Calian helical antennas are well suited for precise point positioning (PPP) and real-time kinematic (RTK) applications on lightweight vehicles such as uncrewed aerial vehicles (UAVs), uncrewed ground vehicles (UGVs), and robotics. Features: Extreme lightweight design, ranging from 4 g to 45 g Novel helical antenna element delivering excellent axial ratio and multipath rejection Excellent gain and axial ratio from zenith to horizon over all azimuth angles High gain LNA combined with an integrated pre-filter Broad GNSS band coverage, including single, dual, triple, full band coverages alongside L-band correction services Robust, military-grade, IP67-or-greater-compliant plastic enclosure Available in housed and embedded models Iridium models available   Applications: UAVs Fixed wing drones and quadcopters UGVs Lightweight robotics RTK applications PPP applications Applications sensitive to multipath effects
