Overview

The CR-G5 choke ring antenna from Topcon is a ground-breaking antenna designed and developed based on Topcon’s new TA-5 full-spectrum GNSS antenna component. The new antenna redefines the “full wave” tracking technology by making it better than ever for existing and future GNSS signals.

Replacing the CR-G3 antenna, the CR-G5 antenna is designed for better signal tracking even at low frequency. It also fulfills requirements of reference networks as well as infrastructure monitoring applications with complete accuracy.

The CR-G5 has been tested to ensure that it withstands the harshest environments including snow, dust and water. It received a IPX7 waterproof and IP6X dustproof ratings and it has also proven to withstand 1 metre drops onto concrete.

Features

  • High-end geodetic antenna
  • TA-5 vertical convex dipole antenna element for full spectrum GNSS signal tracking
  • Topcon designed choke ring ground-plane
  • Environmentally robust and sealed
  • Improved phase-center stability in vertical over expanded GNSS frequency band
