The Topcon CR-G5 Choke Ring Antenna is a highly scalable and robust full wave geodetic antenna.


Product Description


The Topcon CR-G5 Choke Ring Antenna is a ground-breaking choke ring 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 prospected GNSS signals.

Replacing the CR-G3 antenna, the Topcon CR-G5 Choke Ring 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.


  • High-end geodetic antenna
  • Based on TA-5 full-spectrum GNSS antenna for wave GNSS signal tracking
  • Robust, scalable, and accurate
  • Uses an array of vertical convex dipoles for intuitive GNSS signal tracking
  • Centrally stabilized with respect to expanded GNSS frequency band


Due to its outstanding vertical phase center stability, it perfectly supports and tracks signals including:

  • Low elevation satellite signals
  • GPS
  • Galileo
  • Compass
  • QZSS


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. Hence, the Topcon CR-G5 is a perfect choke ring antenna for reference networks and monitoring applications due to its long-term installation design and durability.


The CR-G5 choke ring antenna from Topcon is available through TerrisGPS. If you would like more information regarding this product, feel free to get in touch with us by completing the Request Pricing form.
