SMWG-306 (WiFi, CBRS, GNSS)

Wi-Fi, CBRS, and GNSS Surface-Mount Antenna


The SMWG-306 is a compact vehicle antenna with separate 2.4 GHz Wi-Fi and 3–6 GHz broadband/CBRS paths plus active GNSS.

Key Features

  • Keeps local 2.4 GHz Wi-Fi independent from the broadband radio.
  • Extends the second RF path across CBRS and other compatible 3–6 GHz services.
  • Adds GNSS for navigation, tracking, and timing.
  • Combines all three connections in one IP67-rated roof mount.

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

Product Description

Local Wi-Fi and CBRS. One Position-Aware Mount.

The SMWG-306 gives public-safety, government, and smart-infrastructure platforms a dedicated local Wi-Fi path and a separate broadband connection for compatible CBRS or specialty radios. Active GNSS completes the three-port vehicle antenna.

Separate Local and Broadband Networks: The first element covers 2.4–2.5 GHz for Wi-Fi, while the second spans 3.0–6.0 GHz for compatible CBRS and other broadband equipment.

Specialty-Band Flexibility: The broadband path also reaches compatible military, public-safety, and transportation frequencies across the 3–6 GHz range.

Active GNSS Positioning: The GNSS element supplies navigation, tracking, and timing data independently from both wireless-radio paths.

Protected Multi-Radio Integration: The IP67-rated UV-resistant ASA housing consolidates all three connections and helps keep dust and water away from internal components.

The SMWG-306 keeps 2.4 GHz Wi-Fi, CBRS or specialty broadband, and GNSS available as three independent vehicle connections.

Ideal Applications

  • Mobile CBRS systems
  • Public-safety data networks
  • Military and government vehicles
  • Smart-highway equipment
  • Position-aware field networks
