Overview

From Shenzhen Yonghao Innovation Technology Co., Ltd. (XYZ-GNSS), the YH-301 GNSS Antenna adopts 8-arm coupling and 4-feed-point technology. It supports dual-band (L1/L2) signal reception for BDS-2, GPS, GLONASS, and Galileo, with a built-in low-noise amplifier (LNA) and two-stage filters—ensuring excellent out-of-band suppression, strong anti-interference, and stable work in harsh electromagnetic environments.

Ideal for size/weight-sensitive portable devices (drones, mini RTKs, sub-meter handhelds/tablets), it features a quadrifilar helix design (RHCP polarization, low measurement errors), high gain with minimal roll-off (great low-elevation signal reception), 15 kV air-discharge ESD protection, and easy installation.

Key specs: ≥2.0 dBi peak gain, ≤1.5 dB axial ratio, 35±3 dB LNA gain, 3.0~6 VDC input (3.3 V/5 V recommended, ≤45 mA), SMA-J connector, ABS+PC housing (≤18g), IP67 waterproof, -40~+85℃ operating temp. It meets multi-system compatibility and high-precision measurement needs. *Note: The antenna housing is black.

Key Features
