LTM603 (6x WiFi)

6×6 MIMO Wi-Fi Vehicle Antenna

The LTM603 is a six-element surface-mount vehicle antenna that supports one 6×6 MIMO Wi-Fi radio or two separate 3×3 systems from a single roof-mounted unit.

Key Features

  • Accommodates one 6×6 MIMO radio or two separate 3×3 systems.
  • Expands onboard Wi-Fi capacity with six independently cabled dual-band elements.
  • Distributes omnidirectional coverage across 2.4 GHz and 5 GHz bands.
  • Consolidates six connections at one compact roof mounting point.
  • IP67-rated construction protects onboard connectivity in exposed vehicle environments.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

Six Wi-Fi Paths. One Roof-Mounted Antenna.

The LTM603 places six dual-band Wi-Fi elements in one compact surface-mounted housing for high-order MIMO networks on fleet and transportation vehicles. Compared with installing six separate antennas for the same connections, its single footprint uses less roof space and reduces the number of exterior mounting points.

Flexible 6×6 MIMO Configuration: Use all six elements with one compatible 6×6 MIMO radio or divide them between two separate 3×3 Wi-Fi systems.

Dual-Band Wi-Fi Coverage: Every element covers 2.4–2.5 and 4.9–6.0 GHz, providing six available paths across both Wi-Fi bands.

Single-Housing Integration: The 5.50-inch-diameter housing keeps six connections within one low-profile roof-mounted unit.

Rugged Wi-Fi Protection: IP67-rated construction helps keep dust and water away from internal components, reducing the risk of environmental exposure disrupting onboard Wi-Fi. The antenna operates from −40 °C to +80 °C.

The LTM603 adds high-order Wi-Fi capacity without filling the vehicle roof with separate antenna units.

Ideal Applications

  • 6×6 MIMO vehicle Wi-Fi systems
  • Two independent 3×3 Wi-Fi systems
  • Fleet and transportation vehicles
  • High-capacity onboard wireless networks
