AT Communication is pleased to announce the expansion of its Tactical range of transceivers with the launch of the Sentry-H™ high-frequency (HF), software-defined radio (SDR).
The Sentry-H™ is built using the field proven Envoy HF SDR architecture. The SDR gives operators a secure high-powered software defined radio designed specifically with rugged mil-spec environmental conditions at a competitive price.
The radio provides high-power voice and data in a single radio frequency (RF) unit. The Sentry-H™ delivers second-generation digital voice, uniquely available customisable frequency hopping, embedded GPS, 3G ALE, and IP / USB connectivity.
The Sentry-H™ is suited for both mobile and base configurations without the need for an external amplifier. The system features a smart handset with an intuitive menu system with multiple language options and support for H250 handsets and accessories.
Key features of the Sentry-H™ include:
- Future-proof SDR design
- Rugged smart handset with colour display and integrated GPS
- Multi-language user interface
- Optimised for mobile and base
- 150W PEP
- Wide range of voltage inputs for use with any power source
- Second generation digital voice
- STANAG / MIL-STD-188-110B data waveforms (up to 19k² bps)
- AES-256 digital COMSEC
- Frequency hopping
- MIL-STD-188-141B ALE
- Waterproof MIL-STD-810G construction
- IP / USB connectivity
- Interoperable with 2110M manpack
- H-250 accessories support
- Worldwide service and support
The Sentry-H is suited for military organisations that demand uncompromised, secure long range voice and data communications.
With 150W of RF power, it has been designed in consultation with military users to be small and light for simple integration into new and retrofit vehicle and base station configurations.
Sentry-H is available with an ergonomic smart handset with a color, high-resolution multi-language interface.
Software defined architecture
Sentry-H uses the latest high-performance Digital Signal Processor (DSP), Field-Programmable Gate Array (FPGA) and system on chip (SoC) technology.
Using a field proven SDR platform based upon the Envoy with thousands of hours of operation in the field, Sentry-H delivers market-leading performance and future upgradability via software updates.
Software Defined Architecture enables military signals organisations to install new capabilities, support evolving standards and ensure sustainability.
Rugged and easy-to-use smart handset
The Sentry-H smart handset features a large color display with complete radio and configuration control via the easy to use keypad and icon based menu system. With a loudspeaker mode, built-in GPS receiver / antenna, and USB programming port, the Sentry-H handset provides access to key functionality at the operator’s fingertips.
High power for base and mobile configurations
The Sentry-H is the military industry’s first HF radio delivering 150W of RF power without the added cost, weight and installation complexity of an external amplifier. The in-built power amplifier provides full-duty cycle performance across the complete HF band for all supported modes. Designed for maximum efficiency and a wide range of DC input voltages, the Sentry-H can be used in all vehicle and other battery based systems.
The rugged RF unit is made out of a high-grade metal cast chassis and exceeds MIL-STD-810G providing confidence to communicate no matter what the operating conditions.
Secure voice communications
Sentry-H™ comes with second generation Digital Voice technology providing a significant improvement in High Frequency (HF) voice communications. A full digital mode coupled with highly optimised vocoder technology provides voice quality similar to that experienced with cellular phones. The Sentry-H™ advanced and unique digital voice codec allows it to transmit and receive in signal conditions that competing radios would simply not be able to communicate.
A range of COMSEC options are available with the Sentry-H, from CES-128 grade voice encryption through to full AES-256 encryption of digital voice and STANAG / MIL-STD data. The AES-256 encryption supports 256 by 64 bit keys with additional layers of protection possible by incorporating unique radio IDs.
All voice encryption options for Sentry-H can be activated by a hotkey fully integrated with core radio functions like Selcall and ALE calling to ensure simplicity of operation. It is also possible to configure Sentry to automatically enable encryption on specified networks.
Key management software is used to generate the key files, and key fill software or a USB memory stick may be used to load pre-defined operational parameters into the radio.
Secure chat and email communications
The Sentry-H is hardware ready for data communications and is delivered with a 2,400 bit/s robust data modem as standard. This modem is supported with a chat application which provides peer-to-peer text chat, email, and file transfer with an easy to use menu in multiple languages.
With a software install the Sentry-H may be upgraded to full MILSTD / STANAG data capability with data rates up to 19k² bps with Independent Sideband (ISB) using an HF email application.
IP / Ethernet / USB connectivity
Sentry-H IP based design facilitates remote access and the Handset USB port connection to the transceiver programming application. Alternatively, a conventional USB memory stick can be connected for radio profile setting, security key fill and firmware upgrades in the field.
