How can we help?


Pin based, semihemispherical 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.
