Quectel YEGB001Q1A Antenna

Quectel YEGB001Q1A Antenna delivers multi-constellation, dual-band (L1/L5) positioning in the most demanding environments. This antenna is a GNSS magnet mount, a low-profile active external antenna. The YEGB001Q1A antenna combines active amplification with industrial-grade durability to provide unmatched signal clarity and reliability for applications requiring centimeter-level accuracy. This antenna offers low power consumption and operates at a 1.8V to 5V range, ideal for battery-powered systems. The YEGB001Q1A antenna provides a UV-resistant (UL 746c f1) and flame-retardant (UL 94V-0) housing and is RoHS/REACH compliant. This antenna offers IP67 ingress protection and an extended temperature operation range from -40°C to 85°C. Typical applications include autonomous vehicles, marine, surveying and geodesy, precision agriculture, and industrial IoT.
