LMWG-UMB (Cellular, GNSS)

Cellular and GNSS Low-Profile Antenna


The LMWG-UMB combines 800–2200 MHz cellular coverage and active positioning in a compact surface-mount dome.

  • Covers 800–2200 MHz for cellular, UMTS, and AWS systems.
  • Adds active GPS/GNSS through a separate cable.
  • Operates without a ground plane on metal or fiberglass panels.

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