AH201a-GNSS Spiral Antenna

Ultra-low Power Multi-constellation Multi-band Spiral Antenna

The antenna adopts dobby helix technology to ensure the right circular polarization and phase center performance to reduce the impact of measurement errors.
Antenna unit with high gain and small gain roll-off characteristics, good reception of low elevation satellite signals.
It supports a 1.6V-3.6V power supply and has ultra-low power consumption.
Sophisticated low noise, high gain amplification and excellent out-of-band rejection.
Electrostatic protection: 15KV (air discharge).
Small size and lightweight, easy to carry and install.
