PN-A5

    Unmatched signal tracking and multipath reduction

    Topcon’s newly designed PN-A5 antenna combines the Topcon’s new TA-5 full spectrum GNSS antenna element with an innovative convex impedance ground plane. The TA-5 antenna element utilizes an array of vertical dipoles to provide highly sensitive and stable Full Wave signal tracking for all existing and planned GNSS signals. Topcon’s new convex impedance ground plane provides improved multipath mitigation while providing minimum signal loss for satellites tracked to the horizon.

    Features:

    • High-end Geodetic Antenna
    • Topcon’s TA-5 vertical convex dipole antenna element for full spectrum GNSS signal tracking
    • Topcon newly design semi-hemispherical convex impedance groundplane
    • Environmentally robust and sealed
    • Minimized phase center offset variations in vertical within GNSS frequency band. Improved tracking for low elevation satellites providing reliable signal tracking from the local horizon to zenith.

    Full Spectrum GNSS Antenna

    The PN-A5 antenna is revolutionary technology. It shares the same TA-5 antenna element as the CR-G5 but has a new, pin based, semihemispherical ground plane design assuring excellent SV db Gain to the horizon, where a choke ring antenna generally has drop off at low angles.
