AH201b-GNSS Spiral Antenna

Multi-constellation Multi-band Wide Voltage 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.
  • 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.
