SMW-318 (2x 5G LTE + GPS)

2×2 MIMO 5G/LTE and GPS Antenna

The SMW-318 is a compact surface-mount vehicle antenna that provides two independently cabled 5G/LTE paths and one active GPS connection for cellular MIMO, navigation, and tracking.

Key Features

  • Delivers reliable 2×2 MIMO connectivity across broad Sub-6 5G/LTE ranges.
  • Adds active GPS without another roof-mounted antenna.
  • Consolidates three connections in one compact 4.2-inch radome.
  • Routes each RF path to interior equipment through a dedicated 15-foot cable.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

2×2 Cellular MIMO and GPS. One Compact Mount.

The SMW-318 brings two wideband cellular paths and active GPS together for connected vehicles and remote gateways. Housing all three elements in one 4.2-inch radome reduces the number of separate antennas and exterior mounting points required.

Reliable 2×2 MIMO Connectivity: Two independently cabled elements cover 617–960 and 1710–6000 MHz for compatible 2×2 5G/LTE routers and gateways.

Active GPS Built In: A separate 1575.42 MHz GPS element with a 26 dB LNA supplies position data without adding another exterior antenna.

Three Connections, One Surface Mount: Both cellular paths and GPS share one compact stud-mounted housing, preserving mounting space for other vehicle or enclosure equipment.

Flexible Interior Routing: Three dedicated 15-foot cables connect the exterior antenna to radio and positioning equipment installed farther inside the vehicle or cabinet.

The SMW-318 combines cellular MIMO and GPS when a connected platform needs three RF paths from one compact mounting location.

Ideal Applications

  • Fleet and transportation vehicles
  • 2×2 5G/LTE vehicle routers
  • Telematics and asset tracking
  • Remote cellular gateways
  • Navigation-enabled mobile equipment
