Trimble SNR43x GNSS Radio for Machine Control

The SNR43x provides dependable wireless data transfer between your GNSS base stations and machine-mounted receivers. Available in dual-band configurations, the radio supports both 450 MHz and 2.4 GHz frequency options to accommodate your project requirements and regional licensing regulations. 

With a receive sensitivity of -108 dBm in the 450 MHz band and data rates up to 19,200 bps, the SNR43x maintains reliable connections over typical jobsite distances of two to five kilometers. The integrated 2.4 GHz band extends this capability with 460 kbps throughput for rapid data exchange with universal total stations.

Built to withstand demanding construction environments, the SNR43x combines technical performance with practical durability:

• Rugged, sealed housing: IP67-rated waterproof enclosure protects internal components from dust, rain, splash and spray while withstanding operating temperatures from -40°F to +158°F.
• Multiple system compatibility: Works with Trimble grade control solutions, including GCS900 v10+, SiteVision GPS, BladePro 3D and other machine control platforms.
• Flexible power operation: Suitable for both 12V and 24V DC systems (9 to 32 VDC range) with reverse polarity protection and load dump protection.
• Field-upgradeable software: Update firmware as needed to support new features and maintain compatibility with Trimble positioning technology.

The radio includes flexible rubber-duck-style antennas and mounts that use a standard bracket compatible with Trimble 3D grade control installations. An LED status indicator provides at-a-glance information about radio operation.

The SNR43x integrates into your broader Trimble GNSS systems to ensure dozer operators, motor grader crews and paving teams have continuous access to design information and real-time grade guidance. When you're running GPS-only base station setups, the 450 MHz band is used to transmit correction data over longer distances. For projects that combine GPS positioning with UTS tracking, the dual-band configuration allows both data streams to operate simultaneously.
