Furuno AU-117 GPS Timing Antenna

The Furuno AU-117 GPS timing antenna is designed especially for timing GPS receivers and GPS-steered frequency generators. It is ideal for use in locations with intense electric field.


  • Antenna for GPS signal reception (L1 band)
  • The antenna consists of the antenna for receiving GPS signal, the filter for band limitation and the preamplifier for signal amplification.
  • Power supply for preamplifier operation is supplied by overlapping the signal line.
  • Wide range of power supply from 4VDC to 13VDC.
  • Easy installation by using optional antenna fixing bracket.
