The Trimble® Tornado™ external dual frequency antenna contains advanced technology for extremely low multipath, outstanding low elevation satellite tracking, and high phase center accuracy. Use the Tornado antenna together with a Trimble H-Star enabled handhelds and receivers for high-accuracy mapping and GIS data collection.
The Tornado antenna can be mounted on a range pole—along with the Geo7X handheld—to give you a convenient all-on-the pole solution. An optional magnetic mount allows it to be directly mounted on the roof of a vehicle.
