DMR TB9300 Base Stations/Repeaters

  1. The Tait TB9300 Base Stations are conventional or trunked, IP connected, digital base stations for DMR Tier 2 or Tier 3 networks. The functionality of these base stations allows for flexible network designs and easy migration paths from analog networks to DMR.

    These spectrally efficient base stations provide a 6.25kHz equivalent operation using 2 x TDMA channels in one 12.5kHz channel, giving you greater capacity now and providing a future path for expansion.

    The TB9300 also provides operational efficiencies through remote network management and IP connectivity capabilities.

    High performing, tough and resilient networks
