This high-performance combination antenna is designed for reliable connectivity in demanding environments. It supports both 4G/LTE cellular and GNSS (GPS, Galileo, GLONASS, QZSS) technologies, making it ideal for applications such as asset tracking, fleet management, telematics, and industrial IoT. The magnetic mount allows for quick and secure installation on metal surfaces, while the robust housing ensures durability in harsh outdoor conditions. With IP67 and IP69K protection, this antenna is well-suited for automotive, transportation, and mission-critical deployments.
