This high-performance marine antenna is designed for reliable satellite communication and navigation, supporting both GNSS (GPS, QZSS, Galileo) and Iridium networks. Its ground plane independent design ensures consistent performance in challenging environments, while the compact and robust construction makes it ideal for marine, transportation, and remote monitoring applications. The antenna is Iridium certified and features IP67 protection for durability in harsh conditions.
