TOPCON PN-A5
​PIN BASED, SEMI-HEMISPHERICAL GROUND PLANE GNSS ANTENNA

The PN-A5 antenna combines the Topcon 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.

Revolutionary Semi-Hemispherical GNSS Antenna
Unmatched Signal Tracking And Multipath Reduction
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.

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.

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.
