LTMG402 (2x 4G LTE, 1x WiFi, GNSS)

LTE, Wi-Fi, and GNSS Vehicle Antenna

The LTMG402 is a four-element low-profile vehicle antenna that supports 2×2 LTE, a separate dual-band Wi-Fi connection, and active GNSS from one roof-mounted unit.

Key Features

  • Delivers reliable 2×2 LTE connectivity across low-band and higher-frequency ranges.
  • Adds a dedicated dual-band Wi-Fi path for onboard equipment.
  • Integrates multi-constellation GNSS for navigation and tracking.
  • Consolidates four RF connections at one compact mounting point.
  • Rugged housing protects cellular, Wi-Fi, and GNSS connections in harsh conditions.

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

Product Description

2×2 LTE, Wi-Fi, and GNSS in One Mount.

The LTMG402 brings cellular data, onboard Wi-Fi, and positioning into one low-profile vehicle antenna. Its four independently cabled elements give compatible fleet routers two LTE paths, one Wi-Fi path, and active GNSS from a single roof-mounted unit.

2×2 LTE MIMO: Two cellular elements cover 694–960 and 1710–3700 MHz for compatible 2×2 LTE routers and gateways.

Dedicated Dual-Band Wi-Fi: A separate Wi-Fi element covers 2.4–2.5 and 4.9–6.0 GHz for onboard wireless equipment.

Integrated GNSS Positioning: The active GNSS element supports GPS, Galileo, GLONASS, QZSS, and BeiDou without requiring another roof antenna.

Rugged Multi-System Protection: The IP69K-rated stud mount helps keep dust and high-pressure water from reaching internal components. UV-inhibitive ASA, corrosion-resistant aluminum, and a −40 °C to +80 °C operating range protect against sun, moisture, extreme heat, and cold.

The LTMG402 provides the core cellular, Wi-Fi, and positioning connections used by many connected fleet platforms without adding multiple exterior housings.

Ideal Applications

  • 2×2 LTE fleet routers
  • Connected transportation vehicles
  • Onboard Wi-Fi systems
  • Vehicle navigation and tracking
