MA252.A.LB.001 Antenna External 4G/LTE, GNSS adhesive mount Sentinel 2-in-1 IP67 for HD video over LTE, First Responder and Emergency Services, Automotive vehicle tracking, Telematics

The Sentinel MA252 is a compact 2-in-1 external antenna that combines cellular LTE connectivity with active GNSS positioning in a single low-profile housing. Designed for vehicle and M2M deployments, it supports reliable connectivity and accurate positioning while enabling an in-cabin mounting option on glass or plastic surfaces.

• 2-in-1 design: cellular + GNSS in one housing for simplified integration
• Vehicle-focused mounting: intended to mount directly to glass or plastic using adhesive
• Ruggedized enclosure: IP67-rated for demanding environments
• Use cases: telematics, vehicle tracking, emergency services connectivity, and LTE video applications
