This low-profile antenna offers reliable 4G/LTE cellular and GNSS performance in a compact form factor, making it ideal for installations where space is limited. Its ground plane independent design allows for flexible mounting on a variety of surfaces, including plastic and metal enclosures. The robust housing with IP67 and IP69 protection ensures durability in harsh outdoor environments, while the UV-resistant materials provide long-term reliability. The antenna is suitable for applications such as fleet management, connected vehicles, public transportation, gateways, routers, and location-based services.
