Ultra-narrowband solutions for mission critical networks

The Tait TB9300 is our trunked IP connected DMR digital base station, building on the leadership role that we established with our MPT TB8100. The TB9300 provides 6.25kHz equivalent operation and is fully compliant with theDMR Tier 3 trunking standard.

The TB9300 is a true spectrally efficient solution, allowing you to gain greater capacity, and future proof your investment. It also gives you deployment and operational efficiencies through capabilities such as remote network management and IP connectivity.

The TB9300 is at the heart of the Tait mission-critical DMR system

  • Flexible network design through IP connectivity and linking
  • Individual and group calling to suit operational requirements

Delivers on the goals driving the DMR standards
