ANN-MB-01

Antennas RF Overview

The u-blox ANN-MB-01 is a multi-band active GNSS antenna designed for high-precision positioning applications. It features an RHCP dual-feed patch antenna element integrated with a built-in high-gain Low Noise Amplifier (LNA) and SAW pre-filtering. The unit includes a 5-meter cable terminated with an SMB connector. It supports dual frequency bands: 1.197GHz to 1.249GHz and 1.559GHz to 1.606GHz, enabling compatibility with GPS, GLONASS, Galileo, BeiDou, and other major global navigation satellite systems.

Antennas RF Feature Summary

• Includes a 5-meter RG174 cable with an SMB connector for direct interface
• Supports dual frequency bands covering L1 and L2/E5b/B2I ranges

Antennas RF Applications

• High-precision RTK positioning systems
• Multi-constellation GNSS receivers
• Surveying and mapping equipment
• Agricultural automation guidance

Antennas RF Procurement Notes

Verify the specific suffix of the part number to confirm connector type and cable length variations within the ANN-MB series. Ensure the receiving system matches the required impedance and voltage specifications for the integrated LNA. Confirm IP rating requirements if outdoor exposure is anticipated, as variants may differ in environmental sealing standards.

Antennas RF Selection Notes

Select this model when dual-band L1/L2 reception is required for ionospheric correction and centimeter-level accuracy. The integrated LNA and SAW filter simplify RF design by providing signal conditioning directly at the source. Consider the 5-meter cable length for installation flexibility between the antenna mount and the receiver unit.

Antennas RF Part Context

The ANN-MB-01 belongs to the u-blox ANN-MB series of multi-band active GNSS antennas. This series is engineered to support modern multi-frequency, multi-constellation platforms, offering robust performance for applications demanding high availability and precision in diverse operational environments.

Antennas RF Replacement Considerations

ANN-MB-00 offers similar dual-band capabilities but utilizes an SMA connector instead of SMB. Verify connector compatibility before substitution. Other models in the ANN-MB family may offer different band configurations or cable lengths.
