Superior Performance and Accuracy

The innovative design of this 3D antenna improves low elevation tracking. An insert was added to the choke ring design to enhance multipath rejection based on results from live GIOVE-A, GIOVE-B and L5 signals.

Proven Robust Technology

Utilizing an ultra-wideband Dorne-Margolin antenna element, our GNSS-750 optimizes antenna gain, enabling use with most manufacturers' geodetic receivers. Its sturdy aluminum alloy construction ensures it will withstand difficult environmental conditions.

Note: The GNSS-750 Antenna is not within the scope of the RoHS Directive. It is intended to be used as a Reference Station antenna at a fixed location, over a long period of time, and as such it qualifies to use the “Large-Scale Fixed Installation” RoHS scope exemption.
