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).
