GNSS L1/L5 Multi-Band High Precision Antenna - 5m (SMA)

The u-blox ANN-MB1 multi-band (L1/L5/E5a/B2a/NavIC) active GNSS antenna is designed to reduce time-to-market for the new generation of high precision GNSS applications, which require highly accurate location abilities. The compact design, excellent price-to-performance ratio, and versatile mounting choices provide customers with fast, easy, and reliable multi-band antenna solutions. The ANN-MB1 antenna is a perfect match to the u-blox F9 platform (including NEO-F9P-15B, ZED-F9P-15B, and ZED-F9T-10B), supporting L1 and L5 bands, thus providing customers with the valuable antenna solution they need to minimize evaluation and design-in efforts.

The ANN-MB1 includes a high-performance multi-band RHCP dual-resonance, dual-feed patch antenna element, a built-in high-gain LNA with SAW pre-filtering, and a 5-meter antenna cable with an SMA connector.
