LTMG942 (4x LTE, 2x WiFi 6E, GNSS)

LTE, Wi-Fi 6E, and GNSS Antenna

The LTMG942 is a seven-element low-profile vehicle antenna that supports flexible four-path LTE, 2×2 Wi-Fi 6E, and active GNSS from one roof-mounted unit.

Key Features

  • Accommodates one 4×4 LTE radio or two independent 2×2 radios.
  • Expands onboard Wi-Fi capacity with a separate 2×2 Wi-Fi 6E connection.
  • Adds multi-constellation navigation and tracking without another roof antenna.
  • Consolidates seven RF connections to preserve roof space for other equipment.
  • Rugged housing protects cellular, Wi-Fi, and GNSS connections in harsh conditions.

Product Description

Seven Connections. LTE, Wi-Fi 6E, and GNSS.

The LTMG942 combines four LTE paths, two Wi-Fi 6E paths, and active GNSS in one low-profile roof-mounted antenna for fleet and transportation vehicles. Its seven-element architecture supports flexible cellular, onboard wireless, and positioning connections while preserving roof space for other equipment.

Flexible LTE Connectivity: Four independently cabled LTE elements support one compatible 4×4 radio or two separate 2×2 radio groups.

2×2 Wi-Fi 6E Support: Two Wi-Fi elements cover 2.4–2.5 and 4.9–7.2 GHz with 5 dBi gain for compatible onboard 2×2 equipment.

Integrated Multi-Constellation GNSS: The active positioning element supports GPS, Galileo, GLONASS, QZSS, and BeiDou without another roof-mounted 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 LTMG942 provides flexible cellular capacity, 2×2 Wi-Fi 6E, and positioning in one compact vehicle antenna.

Ideal Applications

  • 4×4 LTE vehicle routers
  • Dual 2×2 cellular radio installations
  • 2×2 onboard Wi-Fi 6E networks
  • Vehicle navigation and tracking
