LTMG940 (4x LTE, GNSS)

4×4 MIMO LTE and GNSS Antenna

The LTMG940 is a five-element low-profile vehicle antenna that supports one 4×4 LTE radio or two 2×2 cellular groups plus active GNSS from one roof-mounted unit.

Key Features

  • Accommodates one 4×4 LTE radio or two independent 2×2 radios.
  • Covers low-band and higher-frequency LTE from four cellular elements.
  • Adds multi-constellation navigation and tracking without another roof antenna.
  • Consolidates five RF connections to preserve roof space for other equipment.
  • Rugged housing protects cellular and GNSS connections in harsh vehicle environments.

Product Description

4×4 LTE and GNSS in One Vehicle Antenna.

The LTMG940 gives fleet and transportation vehicles four LTE paths and active GNSS in one low-profile roof-mounted antenna. Its cellular architecture can support one high-order 4×4 connection or two separate 2×2 radio groups without changing the exterior housing.

Flexible Cellular Architecture: Four independently cabled LTE elements support one compatible 4×4 radio or two separate 2×2 groups for single- or dual-radio installations.

Wideband LTE Coverage: Each cellular element covers 694–960 and 1710–3700 MHz with 2 dBi low-band and 5 dBi high-band gain.

Integrated Multi-Constellation GNSS: The active positioning element supports GPS, Galileo, GLONASS, QZSS, and BeiDou without requiring another antenna on the roof.

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 LTMG940 provides flexible four-path LTE capacity and positioning from one compact vehicle antenna.

Ideal Applications

  • 4×4 LTE vehicle routers
  • Dual 2×2 cellular radio installations
  • Fleet and transportation vehicles
  • Vehicle navigation and tracking
