GNSS 3D Wideband Choke-Ring Antenna

An innovative evolution from the traditional 2D choke-ring antenna design, the GNSS-750's unique 3D form factor delivers superior multipath mitigation, high accuracy and exceptional low elevation tracking. The design of the GNSS-750 has been enhanced even further recently to optimize L5/E5a multipath rejection. Extensive testing with the Galileo GIOVE-A and GIOVE-B test satellites and with the GPS L5 demonstration signal conclusively demonstrates 20 dB additional multipath resistance at L5/E5a bands. The GNSS-750 enhancements also virtually eliminate phase center offsets and variations.

The GNSS-750 optimizes antenna gain to allow interoperability with most manufacturers' geodetic receivers. It also incorporates an ultra-wideband Dorne-Margolin antenna element, the industry standard for phase center precision. Made of a sturdy aluminum alloy, the rugged GNSS-750 can withstand severe environmental conditions and will not see the degradation that can occur over time with reference antennas constructed with plastic materials.
