GZY-506 is a high-performance PCB ultra-high frequency antenna with dimensions of 128×128×20mm and a gain of 6dBi. It has an IP67 high protection level, a working temperature range of -40℃ to 60℃, a half-power angle is 65 degrees, and a more concentrated reading directionality. The circular polarization design and low VSWR (≤1.3) ensure stable signal transmission, making it suitable for scenarios with high reliability requirements such as storage, archives, and asset management.
