Codan Sentry-H uses the latest-generation high-performance Digital Signal Processor (DSP), Field-Programmable Gate Array (FPGA) and system on chip (SoC) technology. Built upon a proven SDR platform with thousands of hours of operation in the field, Sentry-H delivers market-leading performance and future upgradability through software updates. It enables organisations to install new capabilities, support evolving standards and ensure sustainability.

In consultation with customers worldwide, The Sentry-H smart handset was designed to meet the unique operational and environmental challenges faced by military radio users.

The handset features a large colour display, and complete radio control and configuration via the easy to use keypad. With a loudspeaker mode, built-in GPS receiver/antenna, and USB programming port, the Sentry-H handset packs functionality and versatility into a rugged and ergonomic form factor.

The Sentry-H is the military industry’s first base and mobile radio system that delivers 150 W of RF power without the added cost, weight and complexity of an external amplifier. The Sentry-H has an in-built power amplifier that 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 is the HF radio of choice for vehicle and other battery based systems.

The rugged RF unit is made out of a high-grade metal cast chassis and meets or exceeds MIL-STD-810G so you can be confident it will get the job done no matter where you operate.

The Sentry-H handset user interface has been designed with ruggedness, and ease of configuration and operation as primary objectives. The intuitive icon-based menu system and easy to read layout, coupled with an ability to switch between multiple native languages (including data entry modes) ensures that you can focus more on your mission and less on complex radio operations and training.
A comprehensive range of ALE call types are supported including selective, message, phone, NET and GROUP calls so the radio can be adapted to specific communications scenarios. Calls can be made ad-hoc or via fully pre-programmed entries in the Contacts list.
Operator access to radio configuration parameters can be easily locked down or made available, depending on your unique circumstances.

Codan’s second generation Digital Voice technology provides a quantum leap 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. With AES-256 encryption, Sentry-H delivers a fully secure, superior quality voice capability.

The Sentry-H is hardware ready for data mode and is delivered with the Codan 2400 bit/s robust data modem as standard. This modem is supported with the Codan Chat application which provides peer-to-peer text chat, email, and file transfer with an easy to use GUI that also supports multiple languages.
With a simple software option, the Sentry-H may be upgraded to full MIL-STD/STANAG data capability with data rates up to 19k2 bps with Independent Sideband (ISB) using the Codan RC50-C HF email application.

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 256 bit keys with additional layers of protection possible by incorporating unique radio identifiers.
All voice encryption options for Sentry can be activated by a single hotkey, and are 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.
Codan Key Management is used to generate the key files, and Codan Key Fill software or a USB memory stick may be used to load the radio.

The Sentry-H can be enabled with Frequency Hopping capability that can prevent third party monitoring of communications that may jeopardise an operation.
The user can select between up to 31 user programmable hop plans, each comprising a hop name, rate, bandwidth and encryption key.
Additional information security can be achieved with the use of one time session PIN’s, and also combining Frequency Hopping with CES-128 voice encryption.

MIL-STD-188-141B ALE
Codan Sentry-H delivers MIL-STD-188-141B ALE and FED-STD-1045 ALE capability as standard, ensuring interoperability with other radios using these protocols. It comes with Codan’s advanced link management technology (CALM™), which improves the performance of standard ALE by time stamping the channel quality (LQA) information. The ALE call system is fully integrated with system capabilities providing a seamless transition between channel linking and subsequent operations such as data transfers.

Sentry-H IP based design facilitates remote access and the Handset USB port provides a convenient point for connecting the Codan TPS-3250 transceiver programming application. Alternatively, a conventional USB memory stick can be connected for radio profiling, security key fill and firmware upgrades in the field.

Codan Sentry-H has embedded GPS receivers in the RF Unit and Handset with GPS, GLONASS and BEIDOU navigation systems supported. The Sentry-H RF Unit has a connection point for an external remote GPS antenna if needed.

Your distance and bearing from a remote HF station or waypoint can be displayed graphically via the handset user interface.
