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.
