The u-blox ANN-MB1 is a multi-band active GNSS antenna supporting L1, L5, E5a, B2a, and NavIC frequency bands. Designed for high-precision positioning applications, it pairs directly with the u-blox F9 platform (NEO-F9P, ZED-F9P, ZED-F9T) and other multi-band GNSS receivers.

The antenna features a high-performance RHCP dual-resonance, dual-feed patch element with a built-in high-gain LNA and SAW pre-filtering. It comes with a 5-metre cable terminated with an SMA connector.
