The Advantech BB-2J7041BGFA-300 is a compact heavy-duty antenna for 4G LTE and GNSS in industrial and vehicle deployments. One Ø 96 x 90 mm dome holds two cellular MIMO elements and a positioning element, each on a separate 3 m cable with an SMA-male connector. The long cables let the router sit deep inside a vehicle or cabinet while the antenna mounts outside. Both LTE elements use low-loss LMR195 cable, and the GNSS element uses LMR100. The cellular elements cover 698-960 MHz (700/850/900), 1710-2170 MHz (1700/1800/1900/2100) and 2500-2700 MHz (2600) for 2G, 3G and 4G. Radiation is omnidirectional with linear polarisation, 50 Ohm impedance and a 25 W maximum input rating. Efficiency measures around 54-63% in the low and mid bands, with peak gain of approximately 4.2 dBi at 1710-2170 MHz on cable 1. The GNSS element receives GPS, QZSS and Galileo at 1575.42 MHz and GLONASS at 1598-1610 MHz. It uses RHCP polarisation, a SAW pre-filter, 28 dB active gain and a 1.8 dB noise figure at 2.7 V, and runs from 1.5-3.6 V. The antenna is ground plane independent, so it performs on fibreglass, plastic or metal surfaces. It has a UV-stable ASA radome on an aluminium alloy base with an anti-rotation mounting system. The housing is certified IP67 for water resistance, IK09 for impact resistance and IP69K for high-pressure, hot-water ingress. Operating range is -40 to +85 °C, and the antenna is RoHS compliant. Advantech lists compatibility with the ICR-2431, ICR-2432, ICR-2441, ICR-2834, ICR-3231, ICR-3232, ICR-3241, SR304, SR305, SR308, SR309 and SR310. A manufacturer datasheet is available for this model.
