Product Description

Essential Fleet Connectivity in One Compact Antenna.

The SMWG-UMB provides a straightforward three-port antenna for fleet gateways that need cellular service, local 2.4 GHz Wi-Fi, and active GNSS. Each function remains independent while sharing one compact vehicle-mounted housing.

Dedicated Cellular Connectivity: The cellular element covers 800–1250 and 1650–2700 MHz for compatible 4G LTE and legacy mobile equipment.

Local Wi-Fi and GNSS: Separate 2.4 GHz Wi-Fi and active GNSS paths provide onboard networking, navigation, and vehicle tracking alongside cellular service.

Three Connections, One Mount: All three RF elements share one 4.2-inch radome, reducing separate antenna units and roof penetrations.

Protection for Fleet Environments: The IP67-rated UV-resistant ASA housing helps keep dust and water away from internal components in mobile installations.

The SMWG-UMB provides the core cellular, local Wi-Fi, and GNSS connections needed by general-purpose fleet gateways.

Ideal Applications

  • General-purpose fleet gateways
  • Vehicle telematics
  • 2.4 GHz onboard Wi-Fi
  • Mobile cellular equipment
  • Navigation and vehicle tracking

Example Model Configurations: SMWG-UMB-003C2C-WHT-180, SMWG-UMB-3C002C-WHT-180, SMWG-UMB-3C3C2C-WHT-180
