MA251.A.BI.001 Antenna External 2x2 MIMO 4G/LTE adhesive mount Sentinel IP67 for HD video over LTE, First Responder and Emergency Services, Automotive vehicle tracking, Telematics

The Sentinel MA251 is a compact, low-profile 2-in-1 cellular MIMO antenna designed for in-vehicle and telematics deployments where strong LTE performance is needed without a roof-mount solution. It supports worldwide 4G LTE bands and provides fallback coverage for common 3G and 2G networks, making it well-suited for transportation and remote monitoring use cases.

Its adhesive mounting design enables placement directly onto glass or plastic surfaces, providing a convenient in-cabin mounting approach while maintaining high efficiency and strong MIMO performance.
