TB9300 Base Station

The Tait TB9300 is an IP connected, digital base station for DMR Tier 2 (conventional) or Tier 3 (trunked) networks. Their functionality 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 two TDMA channels in one 12.5kHz channel, giving you greater capacity now and providing a future path for expansion.

Why choose TB9300?


Smooth Migration

Tait has the best migration stories around. The TB9300 operates in multiple modes, including Analog Conventional, MPT-1327, DMR Tier 2, and DMR Tier 3. You can install the base station to operate on your existing network today, and then upgrade with ease when ready.


Receiver Performance

The TB9300 offers exceptional receiver performance and exceeds or matches all other DMR base stations on the market for sensitivity, selectivity and intermodulation performance. This means that the user gets extended talk-in (uplink) range as well as significantly increased resistance to interference for clearer, more consistent audio.


Operational effiency

The TB9300 provides operational efficiencies through remote network management and IP connectivity capabilities, which includes alarm monitoring and reporting, inbuilt diagnostics, and remote software downloads. It also supports packet data over traffic channels for Workforce Management, Telemetry, SCADA and other applications.



The remote network management is utilized with built-in secure https web server and SNMPV3 support. The TB9300 also offers enhanced security through password protection and access level control on the web server. Multiple user accounts with varying access can be maintained, and audit and system logs can be retained.


Resilient, reliable communications

To give you confidence in your communications in even the most challenging environments, the TB9300 is rated for continuous full output power and ensures continuity of operation with smart AC/DC management. With support for up to two base station software releases, it gives you the ability to roll-back software updates. Like all Tait products, it's built Tait Tough and meets relevant MIL-STD-810G test methods.


Easy to Maintain

The modular design of the TB9300 allows cost-effective deployment, maintenance, and upgrades. It is software configurable, including feature upgrades through software licenses, and software upgrades can add new features and functionalities to ensure that your DMR solution is kept up to date with the ever-changing needs of your organization's environment.



Control, customize, and enhance base station operations with TaskBuilder, by creating rules that extend the functionality of the base station. Rules can control channel changes, digital outputs, timers, and alarms, based on events and external signals.
