The ERF4148 is a robust multi-band GNSS antenna built for high-accuracy positioning in challenging outdoor environments. With support for GPS L1/L2, GLONASS G1, Galileo E1/E5b, BeiDou B1/B2, and QZSS L1/L2c, it ensures reliable performance across global satellite systems.
Designed for integration in applications like fleet tracking, autonomous systems, agriculture, and industrial IoT, this active antenna combines high LNA gain (28 dB), low noise figure (2.5 dB), and IP67-rated housing. Its RHCP polarization and excellent out-of-band rejection make it ideal for noise-sensitive designs.
Mountable via nut fixation and equipped with a TNC connector, the ERF4148 is engineered for long-term durability, even in harsh conditions.
