LTMG408 (2x 5G/LTE, 1x WiFi 6E, GNSS)

5G/LTE, Wi-Fi 6E, and GNSS Antenna

The LTMG408 is a four-element low-profile vehicle antenna that supports 2×2 5G/LTE, a separate Wi-Fi 6E connection, and active GNSS from one roof-mounted unit.

Key Features

  • Delivers reliable 2×2 5G/LTE connectivity across broad Sub-6 ranges.
  • Extends onboard Wi-Fi connectivity through Wi-Fi 6E and Wi-Fi 7 spectrum.
  • Adds multi-constellation navigation and tracking without another roof antenna.
  • Consolidates four RF connections at one compact mounting point.
  • Rugged housing protects cellular, Wi-Fi, and GNSS connections in harsh conditions.

Product Description

5G/LTE, Wi-Fi 6E, and GNSS in One Vehicle Mount.

The LTMG408 integrates 2×2 5G/LTE, wideband Wi-Fi, and active GNSS in one low-profile roof-mounted antenna for connected fleet and transportation vehicles. Four separate antenna paths support the vehicle router, onboard wireless equipment, and positioning system from one exterior housing.

Wideband 2×2 Cellular: Two independently cabled elements cover 617–960 and 1710–6000 MHz for compatible 2×2 5G Sub-6 and LTE routers.

Wi-Fi 6E and Wi-Fi 7 Ready: The dedicated Wi-Fi element covers 2.4–2.5 and 4.9–7.2 GHz for compatible equipment using 2.4, 5, and 6 GHz Wi-Fi spectrum.

Multi-Constellation GNSS: The active positioning element supports GPS, Galileo, GLONASS, QZSS, and BeiDou for navigation and tracking.

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 LTMG408 is a compact four-port option for vehicles that need 2×2 wideband cellular, one Wi-Fi connection, and GNSS.

Ideal Applications

  • 2×2 5G/LTE vehicle routers
  • Connected fleet and transportation vehicles
  • Onboard Wi-Fi 6E or Wi-Fi 7 equipment
  • Vehicle navigation and tracking
