Overview

From Shenzhen Yonghao Innovation Technology Co., Ltd. (XYZ-GNSS), the YH-215 GNSS Antenna leverages multi-arm coupling and 4-feed-point technology. It supports dual-band (L1/L5) signal reception for BDS-2, GPS, GLONASS, and Galileo, with a built-in low-noise amplifier (LNA) and multi-stage filters—ensuring strong anti-interference and stable performance in harsh electromagnetic environments.

Ideal for size/weight-sensitive portable devices (drones, mini RTKs, sub-meter handhelds/tablets), it features quadrifilar helix design (RHCP polarization, low measurement errors), good low-elevation signal reception, low power consumption, and easy installation.

Key specs: ≥0dBi peak gain, ≤1.5dB axial ratio, 25±3dB LNA gain, 2.5~16VDC input (≤10mA), SMA-J connector, ABS+PC housing (≤15g), IP67 waterproof, -40~+80℃ operating temp. It meets multi-system compatibility and high-precision measurement needs.

Key Features

Multi-GNSS Dual-Band Coverage

Simultaneously supports BDS B1/B2a (1561/1176MHz), GPS L1/L5 (1575/1176MHz), Galileo E1/E5a (1575/1191MHz), and GLONASS L1 (1602MHz) signals for global positioning reliability across diverse geographic regions.

Advanced Spiral Antenna Technology

Quadrifilar helix design delivers superior RHCP polarization with ≤1.5dB axial ratio and <10° phase center variation, ensuring centimeter-level accuracy in RTK surveying and UAV navigation applications.

Ultra-Compact Form Factor

Meticulously engineered with dimensions of only Φ28.5×12mm and weighing ≤15g, featuring SMA-F connector for seamless integration into portable RTK terminals, handheld devices, and micro UAV systems.

Industrial-Grade Durability

Built to withstand extreme conditions with IP67 waterproof rating, operating temperature range of -40℃ to +80℃, and ≤10mA ultra-low power consumption for uninterrupted performance in harsh field environments.
