This compact 3-in-1 antenna is designed for reliable connectivity across 4G/LTE cellular, GNSS satellite navigation, and 2.4 GHz Wi-Fi/ISM bands. Its low-profile, ground plane independent design makes it ideal for applications where space is limited, such as asset tracking, telematics, IoT, and smart devices. The antenna is IP67 rated for robust outdoor or industrial use, and supports a wide range of wireless standards for versatile integration.
