SMWG-412 (LTE, 2x WiFi, GNSS)

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

The SMWG-412 is a four-connection vehicle antenna with one LTE path, two independently cabled Wi-Fi/high-frequency paths, and active GNSS for multi-radio mobile gateways.

Key Features

  • Keeps LTE backhaul independent from two wireless-radio connections.
  • Accommodates separate Wi-Fi, public-safety, military, or transportation roles.
  • Adds GNSS for navigation, tracking, and position data.
  • Consolidates four connections in one IP67-rated surface mount.

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

Product Description

LTE Backhaul and Two Wireless Paths. One Mount.

The SMWG-412 serves mobile gateways that need cellular backhaul and two separately assigned high-frequency radio connections. Active GNSS joins all three data paths in one compact surface-mount antenna.

Dedicated LTE Backhaul: The cellular element covers 694–894 and 1700–2700 MHz for compatible 4G LTE and legacy mobile equipment.

Two Independent Wireless Roles: One wireless path covers 2.4–2.5 and 4.9–6.0 GHz, while the second extends across 2.1–2.5 and 4.4–6.0 GHz for compatible specialty radios.

GNSS Positioning Built In: Active GNSS supplies navigation, tracking, and location data without another roof-mounted antenna.

Protected Four-Port Integration: The IP67-rated UV-resistant ASA housing consolidates all four paths and routes each connection through a dedicated 15-foot cable.

The SMWG-412 keeps LTE, two wireless-radio roles, and GNSS independently connected through one vehicle mount.

Ideal Applications

  • Multi-radio public-safety gateways
  • Fleet communications platforms
  • Vehicle Wi-Fi systems
  • Military and transportation radios
  • Position-aware mobile networks
