SMWG-402 (LTE, WiFi 2.4, WiFi 2.4/5, GNSS)

Cellular, Two-Port Wi-Fi, and GNSS Antenna

The SMWG-402 is a compact vehicle antenna with cellular backhaul, dedicated 2.4 GHz Wi-Fi, a separate dual-band Wi-Fi path, and active GNSS.

Key Features

  • Separates local 2.4 GHz access from a second dual-band wireless role.
  • Maintains dedicated cellular backhaul and GNSS connections.
  • Routes four independent RF paths through one roof-mounted housing.
  • IP67-rated construction helps protect multi-radio connectivity in mobile environments.

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

Product Description

Four Connections for Multi-Radio Vehicle Gateways.

The SMWG-402 adds a second wireless-radio path to the cellular, Wi-Fi, and GNSS combination used by many mobile gateways. One Wi-Fi element is dedicated to 2.4 GHz, while the other extends into higher-frequency WLAN and specialty services.

Two Distinct Wi-Fi Roles: One element covers 2.4–2.5 GHz, and the second covers 2.4–2.5 and 4.9–6.0 GHz for independently connected wireless equipment.

Cellular Backhaul and GNSS: Dedicated cellular and positioning paths keep wide-area service and location data available alongside both Wi-Fi connections.

Four Paths, One Roof Mount: All four elements share one compact 4.2-inch housing, reducing separate antenna bodies and mounting points.

Protected Mobile Integration: The IP67-rated UV-resistant ASA radome helps keep dust and water from internal components across vehicle installations.

The SMWG-402 fits gateways that need cellular, two separate Wi-Fi roles, and GNSS from one compact exterior antenna.

Ideal Applications

  • Multi-radio fleet gateways
  • Vehicle Wi-Fi systems
  • Public-safety mobile networks
  • Telematics platforms
  • Position-aware wireless equipment
