Trimble AV28 GNSS Antenna


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, which means in can operate in the most rugged environments.



The Trimble AV28 GNSS antenna is ideal for applications requiring precise triple-frequency positioning such as robotics and guidance of autonomous vehicles.

The AV28 antenna offers full support for GPS L1/L2/L5, GLONASS L1/L2/L3, Galileo E1/E5a+b, and BeiDou B1/B2. 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.

Its IP67 rating, in combination with the triple-frequency operations, increased system accuracy, good signal to noise ratio and advanced multipath rejection, make the AV28 an accurate and dependable solution.
