ANN-MB2 AllBand+ high precision GNSS antenna
 
The u-blox ANN-MB2 all-band+ (L1/L2/L5/E6/B3/L) active GNSS antenna is designed to reduce timeto-market for the modern wide-frequency, multi-constellation, high precision GNSS applications, which require centimeter-level accuracy and a reliable RTK positioning fix even in challenging environments. The 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 F9 high precision products (e.g. ZED-F9K, ZED-F9P, LEA-F9T, and ZED-F9T) supporting L1, L2, and L5 bands, along with the L-band for RTK corrections. With ANN-MB2, customers have a reliable, ready-to-use all-band antenna that streamlines evaluation, minimizes design efforts, and speeds up mass adoption. ANN-MB2 includes a high-performance, multi-band, RHCP dual-feed stacked-patch antenna element, a built-in high gain LNA with wide-band SAW pre-filtering, and a 5-meter antenna cable with an SMA connector.
