The u-blox ANN-MB2 multi-band (L1/L2/L5/E6/B3/L) active GNSS antenna is designed to reduce time-to-market for modern wide-frequency, multi-constellation, high-precision GNSS applications. Even in challenging environments, these require centimeter-level accuracy and a reliable RTK positioning fix. Its robust design, excellent price-to-performance ratio, and flexible mounting options make the ANN-MB2 an ideal choice for mass market applications requiring an all-band high-precision GNSS antenna.

The ANN-MB2 is a perfect match to the u-blox all-band X20 high-precision platform (e.g., ZED-X20P), and the u-blox F9 high-precision products that support L1, L2, and L5 bands, along with the L-band for RTK corrections (e.g., ZED-F9K, ZED-F9P, LEA-F9T, and ZED-F9T). With ANN-MB2, customers have a reliable, ready-to-use, all-band antenna that streamlines evaluation, minimizes design efforts, and speeds up mass adoption.
