LTMG502 (2x 4G LTE, 2x WiFi, GNSS)

LTE, Wi-Fi, and GNSS Vehicle Antenna


The LTMG502 is a five-element low-profile vehicle antenna that supports 2×2 LTE, 2×2 dual-band Wi-Fi, and active GNSS from one roof-mounted unit.

Key Features

  • Delivers reliable 2×2 LTE connectivity across low-band and higher-frequency ranges.
  • Expands onboard Wi-Fi capacity with a separate 2×2 dual-band connection.
  • Adds multi-constellation navigation and tracking without another roof antenna.
  • Consolidates five 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 and Wi-Fi with Integrated GNSS.

The LTMG502 gives connected fleet and transportation vehicles separate 2×2 paths for LTE and Wi-Fi plus active GNSS in one compact roof-mounted antenna. Its five-element design supports two wireless systems and positioning without requiring multiple exterior housings.

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

2×2 Dual-Band Wi-Fi: Two Wi-Fi elements cover 2.4–2.5 and 4.9–6.0 GHz with 5 dBi gain for compatible onboard 2×2 Wi-Fi equipment.

Integrated GNSS Positioning: The active GNSS element supports GPS, Galileo, GLONASS, QZSS, and BeiDou without adding another antenna to 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 LTMG502 provides balanced cellular, Wi-Fi, and positioning capacity for vehicle systems built around two 2×2 wireless connections.

Ideal Applications

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