SPECIFICATION Part No. : MA250.A.LBI.001 Product Name : Sentinel Adhesive Mount 3in1 LTE MIMO + GNSS Antenna Feature : Ideal for IoT and Automotive Applications Smallest High Performance MIMO • 2 x LTE 4G/3G/2G MIMO 1&2 Antennas • 1 x GPS-GLONASS-BeiDou L1 Active Antenna IP67 Waterproof High Efficiency Low Profile Housing – Only 14mm in Height 2M CFD-200 and RG-174 Cables SMA(M) Connectors Dims: 139*76*14mm RoHS Compliant SPE-16-8-066/A/WY Page 1 of 62 1. Introduction The MA250 Sentinel 3in1 Adhesive Mount 4G LTE MIMO and GPS/GLONASS/BeiDou L1 antenna is an omnidirectional, fully IP67 waterproof external M2M antenna for use in telematics, transportation and remote monitoring applications worldwide. It is designed to be mounted directly on glass or plastic in the interior of vehicles. It is the smallest high performance solution in the market, 50% smaller than the previous generation, with higher efficiency and wider bandwidth to cover emerging LTE bands. Its performance is comparable with much larger permanent roof mount antennas and now offers a convenient and economical alternative in-cabin mounting solution. Typical applications include; HD video over LTE First Responder and Emergency Services Automotive vehicle tracking Telematics It is mounted via high quality, first tier automotive approved, 3M adhesive. In-house world leading dielectric ceramic antenna technology inside allows for smaller size antennas without loss in efficiency. It delivers powerful 2*2 MIMO antenna technology for worldwide 4G LTE bands at 700MHz/ 800MHz/ 1700MHz/ 1800MHz /2300MHz /2600MHz, while allowing fallback to all common worldwide 3G and 2G frequency bands. The antenna has an output for GPS-GLONASS-BeiDou for next generation location accuracy. 4G wireless applications demand high speed data uplink and downlink. High efficiency and high gain MIMO antennas are necessary to achieve the required signal to noise ratio and throughput required to solve these challenges. Taoglas also takes care to have high isolation between the two MIMO antennas to prevent self-interference. Low loss cables are used to keep efficiency high over long cable lengths. SPE-16-8-066/A/WY Page 2 of 62 The IP67 waterproof housing measures just 139*76*14mm with 3M foam adhesive. The antenna can be mounted internally or externally on a vehicle. Both MIMO 1 and MIMO 2 coaxial cables are 2m low loss CFD-200 with SMA(M) connectors. The GPS-GLONASS-BeiDou cable is RG-174 with SMA(M) connector. Customized cable and connector versions are also available. The antenna also comes in a 2in1 LTE/GNSS or a single LTE only variant. Contact your regional Taoglas sales office for support.
