LTMG302 (2x 4G LTE, GNSS)

LTMG302 (2x 4G LTE, GNSS)

2×2 MIMO LTE and GNSS Antenna

The LTMG302 is a low-profile vehicle antenna that provides two LTE paths for 2×2 MIMO and active multi-constellation GNSS from one roof-mounted unit.

Key Features

  • Delivers two LTE paths for reliable 2×2 MIMO connectivity.
  • Covers low-band and higher-frequency LTE from each cellular element.
  • Adds multi-constellation navigation and tracking without another roof antenna.
  • Consolidates three RF connections at one low-profile mounting point.
  • IP69K-rated stud mount protects internal components from dust and water.

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

Product Description

2×2 LTE and GNSS. One Vehicle Mount.

The LTMG302 integrates two LTE elements and active GNSS in one low-profile roof-mounted antenna for fleet and transportation vehicles. It gives compatible vehicle routers a 2×2 cellular connection while keeping navigation and tracking within the same exterior housing.

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

Multi-Constellation GNSS: The active positioning element supports GPS, Galileo, GLONASS, QZSS, and BeiDou at 1561, 1575, and 1602 MHz.

Single Roof-Mounted Unit: Cellular and positioning connections share one 5.50-inch-diameter housing, reducing the number of separate antenna units required on the vehicle.

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 LTMG302 provides a focused cellular-and-positioning solution for vehicles that require 2×2 LTE connectivity.

Ideal Applications

  • 2×2 LTE vehicle routers
  • Fleet-management systems
  • Transportation vehicles
  • Vehicle navigation and tracking
