Furuno AU-217A GNSS Timing Antenna

The Furuno AU-217A GNSS timing antenna is a GNSS  antenna designed for GPS and GLONASS timing products


  • Suitable for use with GT series Timing GPS/GNSS receiver modules and GF series GPS/GNSS Disciplined Oscillators.
  • The antenna assembly consists of a patch antenna for receiving GNSS signals and a preamplifier for signal amplification.
  • Power supply to the antenna preamplifier must be provided by the application on the same RF signal trace as the GNSS RF signal is carried to the application.
  • Wide range of power supply from 2.5 to 16 VDC.
  • Easy installation by using optional antenna fixing bracket.
