PN-A5Full Spectrum GNSS AntennaUnmatched signal tracking and multipath reduction.Topcon’s newly designed PN-A5 antenna combines theTopcon’s new TA-5 full spectrum GNSS antenna elementwith an innovative convex impedance ground plane. TheTA-5 antenna element utilizes an array of vertical dipolesto provide highly sensitive and stable Full Wave signaltracking for all existing and planned GNSS signals. Topcon’snew convex impedance ground plane provides improvedmultipath mitigation while providing minimum signal lossfor satellites tracked to the horizon.• High-end Geodetic Antenna• Topcon’s TA-5 vertical convex dipole antenna elementfor full spectrum GNSS signal tracking• Topcon newly design semi-hemispherical conveximpedance groundplane• Environmentally robust and sealed• Minimized phase center offset variations in verticalwithin GNSS frequency band. Significant increaseof low elevated satellites tracking.
