The ANN-MB multi-band active GNSS antennas from u-blox support signals on the L1 and L2/L5 bands of the four key global navigation satellite constellations (GPS, GLONASS, Galileo, and BeiDou). They deliver a gain of up to 28 dB while operating over a 5 V supply. The antennas measure 60 x 55 x 22.5 mm, have versatile mounting and connector options (SMA, SMB, MCX) and support an extended temperature range of up to 105°C, making them suitable for applications subject to extreme temperatures.
