2J8311BGF 3G, 2G, GNSS, FM screw mount Antenna IP67 IP69

This robust 3-in-1 combination antenna is designed for reliable connectivity across cellular (3G/2G), GNSS (GPS, GLONASS, Galileo, QZSS), and FM radio bands. Its ground plane dependent design and anti-rotation screw mount make it ideal for demanding automotive, telematics, and industrial applications. The antenna features active FM and GNSS elements for enhanced signal performance, and is protected with IP67 and IP69 ratings for use in harsh environments.
