Topcon releases CR-G5 ‘full wave’ geodetic choke ring antenna

Topcon Positioning Systems (TPS) has released the new CR-G5, a high performance choke ring antenna based on the company’s TA-5 full spectrum GNSS antenna element.

Topcon’s new TA-5 technology incorporates an array of vertical convex dipoles to provide “full wave” tracking for all existing and future GNSS signals, said Gavin Docherty, Position Partners GNSS Infrastructure Product Manager.

“This premium geodetic antenna has excellent vertical phase center stability over the entire GNSS frequency band, providing superior performance in tracking low elevation satellite signals,” he said.

“It is environmentally designed for the long-term installations required for reference network and monitoring applications.”


In addition, it is shock tested to withstand repeated 1m drops onto concrete, and is IPX7 waterproof and IP6X dustproof rated.
