Portable Radios

TP9400 & TP9100

More efficient networks. More possibilities.

With multiple operating modes including analog, 12.5kHz P25 Phase 1 FDMA conventional/trunked, upgradable to 6.25kHz (equivalent) P25 Phase 2 TDMA trunked, and LSM (CQPSK) decode capability in a single device, you can transition to a more spectrally efficient solution in a time frame that suits you.

Ensure the safety of your first responders and increase operational effectiveness with TP9400 capabilities such as internal GPS* for location services (over a conventional or trunked network) and Bluetooth ® wireless technology* for accessory connectivity. With additional Man Down and Lone Worker functionality, and AES encryption capability, your first responders can work confidently, knowing their communications are secure.

Tait products are known for their rugged build, and the TP9400 is no exception. The robust design has IP67 sealing and shock absorbing impact-protected corners, exceeds relevant MIL-STD-810G standards, and features a water-shedding grille which aids voice clarity in wet environments.

The TP9400 provides:

  • Operation in VHF and 700/800MHz frequency bands
  • Minimized risk with multi-mode operation for staged migration
  • Greater vendor choice, increased competition and interoperability with adherence to the P25 standards and software-upgradability to P25 Phase 2
  • Efficient operations with encryption, voice and data, simulcast support and pre-set status messages
  • Security-focused fleet management with Over-the-air Rekeying (OTAR) and Tait Key Fill Device (KFD) support

Tait TM9400

TM9400 & TM9100

More efficient networks. More possibilities.

Each TM9400 features multiple modes of operation, including analog, 12.5kHz P25 Phase 1 FDMA conventional/trunked, upgradable to 6.25kHz (equivalent) P25 Phase 2 TDMA trunked and LSM (CQPSK) decode capability, for ease of migration to a more spectrally efficient solution when required.

For safe, secure and effective communications on the move, the TM9400 features Lone Worker, a covert microphone and stealth emergency modes as standard. For additional operational security, the TM9400 supports end-to-end encryption (including AES), the Tait Key Fill Device (KFD) and Over-the-air Rekeying (OTAR).

The TM9400 allows you to work the way that suits you best. With multiple configuration options, software licenses for additional features, and programmable function keys, the TM9400 is an efficient addition to any organization.

The TM9400 provides:

  • Operation in VHF and 700/800MHz frequency bands
  • Reduced migration risk with the multiple modes of operation
  • Greater vendor choice, increased competition and interoperability with adherence to the P25 standards and software-upgradability to P25 Phase 2
  • Efficient operations with encryption, voice and data, simulcast support and pre-set status messages
  • Flexible expansion via an options slot for additional capabilities
  • Rugged build with an IP54 rating, water-resistant control head, and exceeding relevant MIL-STD-810G

Base Stations/Repeaters

Tait TB9400 Base Station
