Overview

From Shenzhen Yonghao Innovation Technology Co., Ltd. (XYZ-GNSS), the YH4N57A is a 4-system full-frequency survey antenna that stands out with high gain, miniaturization, high sensitivity, multi-system compatibility, and reliability—perfect for meeting diverse user needs.

It supports GPS (L1/L2/L5), GLONASS (L1/L2/L3), BDS (B1/B2/B3), and GALILEO (E1/E2/E5a/E5b), plus BT/WIFI/4G mobile communication. Ideal for matching various satellite navigation receivers, it’s widely used in geodetic surveying, waterway surveying, precision agriculture, and marine measurement and can be optionally applied in military fields.

Key specs: 5dBi max gain, ≤3dB axis ratio, ±2mm phase center error, 40±2dB LNA gain, ≤2.0 noise figure. It operates on 3.3-15VDC (≤45mA), features MCX-C-JW1.5 (GNSS) and IPEX connectors, and has a compact design (Φ140.5×23.2mm, ≤250g). With a -40~+85℃ operating temp and 95% non-condensing humidity resistance, it delivers stable performance in harsh conditions.
