Overview

Introducing the GM006 GNSS Foldable Helix Antenna from Yonghao Innovation Technology Co., LTD (XYZ-GNSS)—a 4-system multi-frequency solution tailored for surveying and high-precision UAV industries, especially ideal for surveying smartphones and PADs.

This passive antenna supports GPS, BDS, GLONASS, and GALILEO, with excellent low-elevation signal reception to maintain stable satellite connectivity even in heavily occluded environments. Its broad frequency bandwidth (covering BDS B1/B2/B3, GPS L1/L2, etc., including global network B3) boosts system stability, while high out-of-band suppression blocks interference from communication base stations. The foldable design makes it compact (Φ27.5×107.5mm), portable, and easy to use.  

Equipped with a low-noise amplifier (33±2dB gain, ≤1.5dB noise figure) operating on DC3.3~12V (≤50mA), it features an SMA Male connector, SMA tightening mounting, and IP67 protection (after installation). It endures -25~+70℃ operating temps and -40~+70℃ storage temps, delivering reliable, high-precision performance for on-the-go surveying and UAV applications.
