The MA251 Sentinel 2-in-1 adhesive mount 4G 2x2 LTE MIMO antenna is an omnidirectional, fully IP67 waterproof external IoT/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.
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 2x2 MIMO antenna technology for worldwide 4G LTE bands between 700 and 2600 MHz, while allowing fallback to all common worldwide 3G and 2G frequency bands.
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.

3D Patterns
3D radiation patterns provide an intuitive view of how an antenna radiates in three dimensions. Unlike simulations, they are developed by taking 1656 measurements across three axes inside a certified laboratory faciity.
