  • Compatible with any HF, VHF, UHF Radio
  • Ultra-rugged watertight enclosure and rugged connectors
  • Lightweight, small and convenient
  • Built-In AES Encryption for all over-the-air and data-at-rest information
  • Secure Messaging: Chat, QuickText, SMS/MMS, and Email
  • GPS, Compass, Navigation/Position Tracking, and polar map situational awareness display
  • Sunlight-display and automatic ‘night-mode’ (dim to black)
  • QWERTY keyboard with emergency and address book buttons
  • Embedded JITC-certified STANAG 5066 ARQ for NATO interoperability as well as:
    • STANAG 4538 (3G ALE), 4539, 5066
    • MIL-STD 188-141B (App.A), 810F, 461

With its small size, the ultra-rugged, lightweight RT5 Tactical Terminal provides instant,
secure messaging for any radio network with minimal training or set up time. Combined
with the DT Mil System, the RT5 provides the secure messaging applications
needed for digital command and control and extends those capabilities from the brigade
level to the front line.


Using its high performance modem, the DT RTS interfaces via an audio cable
to HF, VHF, or UHF transceivers to provide a gateway to secure intranets for email, and attachments, and via an external GSM modem for SMS/MMS, Chat, and QuickText


Offering an intuitive user interface, the RT5 is simple to use and allows for rapid
deployment of secure messaging applications, regardless of command levels or previous
training. Predefined forms help structure information and drastically reduce the amount
of data transmitted. Messages may be addressed to individuals or multiple recipients,
depending on the service.

Enabling efficient and accurate point-to-point and broadcast data communications,
the RT5 keeps command centers in contact with the mobile force; even when voice communications are not possible


For situational awareness, the RT5 provides a built in GPS receiver and antenna so that position and time information can be sent securely
over the radio network as needed. Pictures and files can be uploaded to the RT5 and attached to emails, providing visual and critical information
from the battlefield.


The robust voice solution is designed for BLOS secure digital voice communication with superior performance in adverse channels. Vocoder rate
is adapted dynamically to allow optimal quality in all channels. Broadcast and Private-Line (point-to-point) modes are supported, as well as late entry.


CHAT and QuickCodes - provide flexibility and robustness, point-to-point or broadcast. Predefined Forms help structure information for
ease-of-use and drastic data compression.

All over-the-air communications, locally stored messages and positions are encrypted. Access to the unit is restricted by means of a
Personal Identification Number (PIN). A Zeroize function is provided from the keypad which erases all used data and keys.



The RT5 can provide a "modem mode" in which it connects
with the DT GATEWAY Software on a PC via the Ethernet port providing end- to-end Email connectivity.
