This rugged combination antenna is designed for reliable performance in demanding environments, supporting both 4G/LTE cellular and GNSS (GPS, Galileo, QZSS) navigation technologies. Its screw mount design ensures secure installation, while the anti-rotation feature and heavy-duty construction make it ideal for automotive, industrial, and outdoor applications. The antenna features a pre-filtered active GNSS element for enhanced signal quality and is protected with high ingress ratings for use in harsh conditions.
