SMWG-313 (2x DSRC, GNSS)

2×2 DSRC/C-V2X and GNSS Antenna


The SMWG-313 is a compact vehicle antenna with two independently cabled 5.9 GHz paths for compatible 2×2 DSRC or C-V2X systems plus active GNSS.

Key Features

  • Delivers two 5.8–6.0 GHz paths for compatible 2×2 V2X equipment.
  • Adds GNSS for vehicle position and connected-transportation data.
  • Offers SMA and FAKRA configurations for different equipment interfaces.
  • IP69K-rated stud-mount construction protects connections from dust and high-pressure water.

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

Product Description

Two V2X Paths. Integrated GNSS.

The SMWG-313 brings two 5.9 GHz communication paths and active GNSS together for connected-vehicle and intelligent transportation systems. Its compact housing reduces separate antenna units while preserving independent RF connections for V2X and positioning equipment.

2×2 V2X Connectivity: Two independently cabled elements cover 5.8–6.0 GHz for compatible 2×2 DSRC or C-V2X equipment.

Positioning Built In: Active GNSS provides vehicle position, navigation, and timing data without another roof-mounted antenna.

SMA or FAKRA Interfaces: Approved configurations provide conventional SMA plugs or keyed FAKRA female connectors for different modem and vehicle integration requirements.

High-Pressure Ingress Protection: The properly installed stud-mount configuration carries an IP69K rating to help keep dust and high-pressure water away from internal components.

The SMWG-313 integrates two V2X paths, active GNSS, and selectable connector interfaces in one compact vehicle antenna.

Ideal Applications

  • Connected-vehicle systems
  • C-V2X equipment
