Production Information

1 Overview

The u-blox ANN-MB multi-band (L1, L2/E5b/B2I) active GNSS antennas are designed to reduce time

to market for the next generation of high precision GNSS applications, which require highly accurate

location information. The compact design, excellent price to performance ratio, and versatile

mounting and connector choices provide customers with fast, easy, and reliable multi-band antenna

solutions. The ANN-MB antenna is a perfect match to the latest u-blox F9 platform, including the

ZED-F9P module, thus providing customers with a valuable antenna solution to minimize design-in

efforts.

The ANN-MB series includes a high-performance multi-band RHCP dual-feed patch antenna element,

a built-in high-gain LNA with SAW pre-filtering, and a 5 m antenna cable with three connector options

(SMA, SMB, MCX).
