AH301H-GNSS Spiral Antenna

Multi-constellation Multi-band L1+L2+L5 Spiral Antenna

  • The antenna employs a multi-arm feedpoint technology to ensure 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.
  • Electrostatic protection: 15KV (air discharge).
  • Small size and light weight, easy to carry and install.
