Portable power for mission-critical communications
The Tait TB7300 Transportable Repeater is built for fast deployment in high-stakes situations — from natural disasters and tactical missions to firegrounds and crime scenes. This rugged, portable solution allows teams to quickly extend their network coverage or establish a dedicated, on-site communications system when existing infrastructure is unavailable.
Powered by the Tait TB7300 multi-mode platform, it supports analog conventional, DMR Tier 2 & Tier 3, and P25 Phase 1 operation, providing seamless interoperability and high spectral efficiency with 6.25 kHz equivalent TDMA performance.
Designed for reliability in challenging environments, the TB7300 Transportable Repeater combines tough construction, rapid setup, and flexible configuration — ensuring teams stay connected when it matters most.

FREQUENCY BANDS
| Frequency | Range | Tait Band | Configuration |
|---|---|---|---|
| VHF | 136-174MHz | B1 | Factory set to 15W (Max 30W* typical) |
| UHF | 400-470MHz | H5 | Factory set to 15W (Max 25W* typical) |
| 700/800MHz | 762-870MHz | K4 | Factory set to 15W (Max 25W* typical) |
*The output power of the transportable unit is reduced due to the duplexer loss. This improves the battery shift life. If the unit is operated in a high duty cycle environment, for example the trunking control channel, output power should be limited to 15W.
