The u-blox ANN-MB5 multi-band (L1/L5/E5a/B2a/NavIC) active GNSS antenna is designed for the new generation of multi-frequency, multi-constellation standard precision GNSS technology, which can achieve the most accurate, reliable, and robust positioning even in challenging environments. ANN-MB5’s compact design, excellent price-to-performance ratio, and easy mounting features ensure a fast, easy, and reliable multi-band antenna solution for mass adoption. ANN-MB5 is a perfect match to the u-blox L1/L5 multi-band meter-level GNSS technology (e.g., F10 standard precision platform), providing you with the ready-to-use, multi-frequency antenna you'll need to minimize the evaluation and design efforts, and speed up time-to-market.

Jargon buster
Plain-language definitions for the technical terms used above.
- Active GNSS antenna
- An active GNSS antenna has a built-in amplifier that needs power from the board. It can improve satellite signal reception, but you need to use an antenna that matches the board’s powered antenna connection.
- B2a
- A BeiDou satellite signal used by newer dual-band GNSS receivers. Support for B2a can improve accuracy and reliability when combined with other GNSS bands.
- E5a
- A Galileo satellite signal band used for higher-performance positioning services. Support for E5a can help dual-band GNSS receivers improve accuracy and reduce errors from atmospheric delay.
- ground plane
- A ground plane is a large area of copper on a circuit board connected to ground. It helps provide a stable return path for signals and is especially important for reducing noise in high-speed connections.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
- L5
- A modern GNSS signal band used by several satellite systems for more accurate and robust positioning. Dual-band receivers that include L5 can often perform better than single-band receivers, especially for RTK and areas with reflected signals.
- SMA
- SMA is a small threaded coaxial (RF) connector widely used to attach antennas and other radio-frequency cables. A device with SMA antenna ports needs antennas or pigtails with matching SMA connectors, or a suitable adapter, to connect to them.
