Details

Topcon G3-A1M Multiple Constellation Antenna
The G3-A1 is a multiple constellation antenna, and based on the corresponding receiver can receive GPS and GLONASS satellite signals.

The G3-A1 is intended for high vibration uses, such as on the top of a machine control mast. The antennas have been tested to extreme vibration specifications and are recommended for the most rugged environments. Why risk placing an expensive electronic receiver at the top of a machine mast. This ruggedized antenna can be used with bulldozers, motor graders, scrapers, milling machines, and other systems.

An optional ground plane can be easily attached to supplement the reduction of multipath signal interference.

Features:

  • Rugged Design
  • GPS and GLONASS
  • Vibration Tested
  • Optional Ground Plane
