From Shenzhen Yonghao Innovation Technology Co., Ltd. (XYZ-GNSS), the YH-201 GNSS Antenna adopts 8-arm coupling and 4-feed-point feeding technology. It supports dual-band (L1/L2) satellite navigation signal reception for BDS-2, GPS, GLONASS, and Galileo systems, with a built-in low-noise amplifier (LNA) and two-stage filters—ensuring excellent out-of-band suppression, strong anti-interference, and stable operation in harsh electromagnetic environments.

Ideal for scenarios requiring compact size and light weight, it fits portable devices like drones, mini RTKs, and sub-meter handhelds/tablets. The quadrifilar helix design guarantees right-hand circular polarization (RHCP) and superior phase center performance (reducing measurement errors), while the antenna unit offers high gain, minimal gain roll-off, and great low-elevation satellite signal reception. It also features 15K air discharge ESD protection.

Key specs: ≥2.0 dBi peak gain, ≤1.5 dB axial ratio, 32±2 dB LNA gain, ≤1.5 dB noise figure, 3.0-12 VDC input (≤45 mA), ≤1.8:1 max output VSWR. With an SMA-J connector, ABS+PC housing, ≤16g weight, IP67 waterproof rating, and -40~+85℃ operating temp, it meets multi-system compatibility and high-precision measurement needs.
