Model: GAF-68GL


Product Description

Small size and ruggedness, demand of vehicle locating and car navigation GPS/GLONASS antenna that will sustain harsh environment.

  • Low noise figure
  • Fully weather proof IPX8
  • Ultra-high Sensitivity
  • Compact construction
  • Excellent temperature stability

Product Feature

The antenna system GAF-68GL is the integration of the high performance GPS patch antenna and a low noise amplifier into state-of-the-art low a very low profile/extremely compact/fully waterproof antenna signal enclosure. When connected to a GPS/GLONASS receiver with +2.5~ 5.5V DC antenna powers it provides excellent signal amplification and out-band-rejection for that receiver.



GPS/GLNOASS antenna with double threaded bolts and through holes for cable routing with course & fine treaded pitch locking for wing-nut fastener and lock-nut to prevent vibrations and un-authorize removal.
