Trimble AV28 GNSS Antenna

Manufacturer: | Category:

The AV28 GNSS antenna from Trimble is a precise triple-frequency, L-band antenna, ideal for dynamic applications such as robotics and autonomous vehicle guidance. This antenna offers an IP67 rating that means it can perform in the most rugged environments.



The AV28 GNSS antenna offers full support for GPS, GLONASS, Galileo and BeiDou. It also supports Trimble RTX and OmniSTAR correction services via L-Band.

Light and small, this antenna offers excellent axial ratio and a tightly grouped phase center variation. It features a precision tuned, twin circular dual feed and stacked patch element.

Superior Multi-path signal rejection is ensured by its unique design. The AV28 is designed for accuracy, thus it also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.
