This low-profile combination antenna delivers reliable 4G/LTE cellular and high-precision GNSS (GPS, GLONASS, BeiDou, Galileo, QZSS) performance in a compact adhesive-mount form factor. Designed for ground plane independence, it is ideal for asset tracking, telematics, IoT, and automotive applications where robust connectivity and accurate positioning are essential. The antenna features active GNSS with pre-filtering for enhanced signal quality and supports a wide voltage range for flexible integration.
