The ANN-MB5 from u-blox is an Active Multi-Band (L1/L5/E5a/B2a/NavIC) active GNSS antenna. It operates from 1559 to 1608 MHz (L1) and 1164 to 1186 MHz (L5/E5a/B2a/NavIC) frequency bands. This RHCP antenna provides a gain of 4.5 dBic (Zenith) with an efficiency of up to 65% (L5 band) and has an axial ratio of 6.3 dB (L5 band). It includes a low-noise amplifier (LNA) with SAW filtering that provides a gain of 16 dB with a noise figure of 2 dB. This LNA provides an out-of-band rejection of up to 45 dB and has a VSWR of 2.0:1. It requires a DC supply from 3 to 5 V and consumes 17 mA of current.
The antenna is available in a magnetic base-mounted housing that measures 49.14 x 46.14 x 15.94 mm and has an SMA (plug) connector with a 3-meter-long RG174 cable.
