LTM944 (4x LTE, 4x WiFi, GPS)

LTE, Wi-Fi, and GPS Vehicle Antenna

The LTM944 is a nine-element low-profile vehicle antenna that supports 4×4 LTE, 4×4 dual-band Wi-Fi, and GPS 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 four independently cabled dual-band elements.
  • Adds GPS navigation and tracking without another roof-mounted antenna.
  • Consolidates nine connections to preserve roof space for other equipment.
  • IP67-rated construction protects multi-radio connectivity in exposed vehicle environments.

Product Description

Nine Connections. One Compact Vehicle Antenna.

The LTM944 brings LTE, onboard Wi-Fi, and GPS into one low-profile roof-mounted antenna for fleet and transportation vehicles. Its nine-element architecture supports multiple vehicle systems while preserving space for other roof-mounted equipment.

Flexible LTE Connectivity: Four independently cabled LTE elements support one 4×4 MIMO radio or two separate 2×2 radio groups for single- or dual-radio cellular architectures.

4×4 Dual-Band Wi-Fi: Four Wi-Fi elements cover 2.4–2.5 and 5–6 GHz with 5 dBi gain for compatible onboard 4×4 Wi-Fi systems.

Integrated GPS: A dedicated GPS element supports vehicle navigation and tracking without adding another antenna housing to the roof. A GPS/GLONASS option is also available for the platform.

Rugged Multi-System Protection: IP67-rated construction helps keep dust and water away from internal components. UV-stable ASA and a −40 °C to +80 °C operating range protect the antenna across exposed vehicle conditions.

The LTM944 balances multi-radio capacity, roof-space efficiency, and environmental protection for connected fleet platforms.

Ideal Applications

  • Fleet and transportation vehicles
  • 4×4 LTE vehicle routers
  • Dual-radio cellular installations
  • 4×4 onboard Wi-Fi networks
  • GPS navigation and vehicle tracking
