Description

The Q25 GNSS Helical Antenna is an active multi-band GNSS antenna based on a Quadrifilar Helix structure, designed for high-precision positioning in multi-constellation systems. The antenna supports signal reception in the L1, L2, and L5 bands for GPS, BDS, GLONASS, and Galileo, increasing the number of tracked satellites and improving positioning stability.

The Quadrifilar Helix structure provides a wide-angle radiation pattern and right-hand circular polarization (RHCP), enhancing reception of low-elevation satellite signals. Compared to traditional patch antennas, this design improves the utilization of low-horizon signals, resulting in higher positioning accuracy in demanding environments.

An integrated amplifier with 37 dB gain and a low noise figure of 1.5 dB supports stable GNSS signal reception. Power is supplied via DC bias through the RF cable. The antenna features an SMA male connector and operates within a voltage range of 3.3 - 16 V DC.

The IP67-rated enclosure enables long-term outdoor operation. The slim and elongated design of the Q25 version provides a compact structure while maintaining full multi-band GNSS functionality.
