Trimble AV28 Triple-Frequency and L-band Antenna

The Trimble AV28 offers full support for GPS L1/L2/L5, GLONASS L1/L2/L3, Galileo E1/ E5a+b and BeiDou B1/B2 as well as Trimble RTX and OmniSTAR correction services via L-Band. It is especially designed for precise triple frequency positioning.

Trimble AV28 features a precision tuned, twin circular dual feed, stacked patch element and offers excellent axial ratio and a tightly grouped phased center variation. This unique design ensures superior multi-path signal rejection. The AV28 also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands.
