SMWG-303 (2xWiFi, GNSS)

2×2 Wi-Fi, DSRC, and GNSS Antenna


The SMWG-303 is a compact vehicle antenna with two independently cabled wireless paths for compatible 2×2 Wi-Fi or DSRC systems plus active GNSS.

Key Features

  • Delivers two wireless paths for compatible 2×2 Wi-Fi or DSRC equipment.
  • Covers 2.4 GHz Wi-Fi and specialty 4.4, 4.9, and 5.9 GHz services.
  • Adds GNSS for navigation, tracking, and field-test position data.
  • Consolidates three connections in one IP67-rated surface mount.

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

Product Description

Two High-Frequency Paths. Integrated GNSS.

The SMWG-303 brings two high-frequency wireless connections and active GNSS together for mobile video, mesh, public-safety, military, and connected-transportation systems. Each RF path remains independently cabled inside one compact vehicle antenna.

Flexible 2×2 Wireless Operation: Both wireless elements cover common 2.4 GHz and 4.9–6.0 GHz ranges for compatible 2×2 Wi-Fi or DSRC equipment.

Extended Specialty-Band Access: One broadband element also reaches 2.1–2.5 and 4.4–6.0 GHz for compatible military, public-safety, and transportation radios.

Active GNSS Positioning: A separate GNSS connection supplies navigation, tracking, and location data without requiring another roof-mounted antenna.

Rugged Multi-Radio Housing: The IP67-rated UV-resistant ASA radome helps protect all three RF paths from dust and water in mobile environments.

The SMWG-303 combines two compatible high-frequency radio paths and GNSS for position-aware mobile networks.

Ideal Applications

  • 2×2 mobile Wi-Fi systems
  • Mobile video and mesh networks
  • Public-safety field communications
  • Connected-transportation trials
  • Military mobile networks
