Description

This robust 2-in-1 combination antenna is designed for reliable performance in demanding environments, supporting both TETRA/UHF and GNSS (GPS, GLONASS, Galileo, QZSS) technologies. Its screw mount and anti-rotation system ensure secure installation, making it ideal for public safety, fleet management, smart cities, logistics, and other mission-critical applications. The antenna is ground plane dependent and features high peak gain for both TETRA and GNSS, with active GNSS circuitry and pre-filtering for enhanced signal quality. With IP67 and IP69 protection, it is suitable for outdoor and harsh conditions.
