Manufacturer: | Category:

The AV33 GNSS antenna from Trimble is a single frequency, robust, high performance, low-multipath GPS antenna with 4-hole bulkhead mounting allowing it to be used in the most rugged of environments. It is an ideal antenna for aerial, ground and marine applications.



The AV33 antenna offers full support for GPS, GLONASS, Galileo and BeiDou. This antenna is ideal for centimeter-level accuracy and supports a wide range of aerial, ground and marine applications in one compact design.

Its superior multi-path signal rejection is ensured by its unique design which prevents inaccurate measurements. The AV33 is designed for high accuracy. Its advanced filtering keeps the GNSS measurements safe from unrequired interference.

There is a TNC connector on the underside of this antenna for easy removal and protection of the attached cable. Its aviation type design means it can be mounted flush or bulkhead with the vehicle surface or on the top of a pole mount which ensures that only the rugged radome is exposed to the elements. This feature makes is perfect for customers building machine control systems.
