AH203-GNSS Spiral Antenna

Multi-constellation Multi-band Wide Voltage Spiral Antenna

  • The antenna employs a multi-arm feed point technology to ensure the right circular polarization and phase center performance to reduce the impact of measurement errors.
  • The antenna unit is characterized by high gain and small gain roll-off, which is good for low-elevation satellite signal reception.
  • Sophisticated low noise, high gain amplification and excellent out-of-band rejection.
  • Small size and lightweight, easy to carry and install.
