L1/L2/L5 HELIX SMA FLEXIBLE ROD ANTENNA

Multi-Satellite Multi-Frequency GNSS Helical Antenna

This multi-satellite, multi-band quadrifilar helix antenna is engineered for high-precision satellite positioning and navigation applications. It supports GPS L1/L2/L5 and BDS B1/B2a frequency bands and incorporates a high-performance LNA together with an integrated filter circuit. With right-hand circular polarization, consistent gain, and an excellent axial ratio, the antenna provides dependable signal reception, including at low elevation angles. Its compact and lightweight design, combined with IP67 protection, makes it suitable for UAVs, RTK modules, handheld terminals, and portable high-precision positioning equipment.
