Description
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.

The Taoglas MA251 Sentinel 2x2 MIMO 4G Adhesive Antenna offers a compact, high-performance solution for telematics, transportation, and remote monitoring applications. Designed for easy interior mounting on vehicle glass or plastic surfaces, this antenna is 50% smaller than previous models yet delivers superior efficiency and bandwidth, covering emerging LTE bands. Its omnidirectional design and IP67 waterproof rating ensure reliable performance in diverse environments.
The MA251 utilises advanced dielectric ceramic technology, enabling a streamlined form without compromising efficiency. Supporting worldwide 4G LTE bands between 700 and 2600 MHz, it also accommodates fallback to common 3G and 2G frequencies, making it versatile for global deployments. The antenna's 2x2 MIMO configuration enhances data transmission with high speed and low latency, essential for today's demanding 4G wireless applications. High isolation between MIMO antennas minimises self-interference, while low-loss cables maintain signal integrity over extended lengths.
Constructed from durable ABS plastic, the MA251 measures 76 x 139 x 14 mm and weighs 0.24 kg. It features two SMA Male connectors and customisable cable lengths for flexible installation. Certified to ISO 9001 quality management standards, the MA251 represents a reliable, efficient, and economical choice for in-cabin antenna solutions.
