Tait TB7300
The TB7300 is Tait's compact 1U slimline DMR base station and repeater, with 100% duty cycle, multi-mode support for DMR, analog, MPT-IP, and P25 via DFSI, and programmable output from 1W to 50W. At 14.8 lbs and 1U rack height, it is designed for both permanent installations in space-constrained equipment rooms and transportable rapid-deployment configurations.
Overview
Budget repeaters marketed for commercial DMR use often carry duty cycle limitations that prevent continuous operation during extended incidents or high-traffic events. When a repeater throttles transmission to protect its hardware, the communications failure happens at exactly the moment the network is under the most load.
The TB7300 runs at 100% duty cycle with no limitations on continuous operation, making it reliable for permanent sites and event communications deployments. Coverage includes VHF 136-174MHz, UHF 400-470MHz and 470-520MHz, and 700/800MHz 762-870MHz. Output is programmable from 1W to 50W (VHF), 1-40W (UHF), and 1-35W (800MHz). Multi-mode operation covers DMR Tier 2 dual voice channels, DMR Tier 3 single-site trunking, Analog Conventional and Repeater, MPT-IP, and P25 dual mode analog and P25 via DFSI interface. Receiver sensitivity is typically -122dBm (0.18uV) at 5% BER, with a guaranteed floor of -120dBm (0.22uV). Up to 4,000 channels are supported.
At 1.7 x 19 x 15.8 inches and 14.8 lbs (6.7 kg), the TB7300 fits a 1U rack slot. Power Save mode reduces standby consumption to under 6W (VHF) or 7W (UHF) when idle. SNMP management and a web UI allow remote configuration and diagnostics. Transportable configuration is available for emergency response and temporary event deployments. Operating temperature is -30 degrees C to 60 degrees C.
Key Features
100% Duty Cycle Operation
The TB7300 operates at 100% duty cycle with no transmission throttling, unlike budget repeaters that limit continuous operation to prevent overheating. This makes the TB7300 reliable for emergency response scenarios, extended events, and high-traffic permanent sites where demand peaks are unpredictable.
Multi-Mode: DMR, Analog, MPT, P25
Runs DMR Tier 2 dual voice channels, DMR Tier 3 single-site trunking, Analog Conventional and Repeater, MPT-IP, and P25 analog and digital via DFSI interface. This single platform covers every protocol combination a commercial or government customer is likely to need, including P25 gateway functionality alongside DMR operation.
1U Slimline, 14.8 lbs
The 1U rack form factor and 14.8 lb weight make the TB7300 practical for space-constrained equipment rooms where a standard 4U base station would not fit. The same compact profile makes it viable for transportable kit bags and rapid-deployment cases for emergency response and temporary communication sites.
Transportable Configuration
A transportable configuration is available for customers who need deployable infrastructure, including emergency management, event communications, and field incident command. The low weight and 1U profile allow it to be integrated into standard transit cases for rapid deployment without specialized transportation requirements.
SNMP and Web UI Management
SNMP management and a built-in web UI allow remote configuration, real-time monitoring, and diagnostic access without requiring on-site presence. For organizations managing multiple remote sites, this reduces the operational overhead of distributed infrastructure and enables faster fault identification and resolution.
Power Save Mode
Power Save mode reduces standby power consumption to under 6W (VHF) or 7W (UHF) when the repeater is not actively transmitting. For permanent sites with high standby time relative to active transmission, this provides a measurable reduction in operating costs and heat output, extending equipment service life.
