    The CR-G5-C is a choke ring antenna with cavity filter based on Topcon’s TA-5 full spectrum GNSS antenna element.

    The TA-5 antenna element utilizes an array of vertical convex dipoles. This antenna provides Full Wave tracking technology for existing and future GNSS signals.

    The antenna addresses the evolving requirements for reference networks and infrastructure monitoring applications.

    Features:

    • High-end Geodetic Antenna
    • Topcon’s TA-5 vertical convex dipole antenna element for full spectrum GNSS signal tracking
    • Cavity filter mitigates near band jamming
    • Topcon designed choke ring groundplane
    • Improved phase center stability in vertical over expanded GNSS frequency band. Improved low elevated satellites tracking
