Sentry-H Portable Kit

SOFTWARE-DEFINED HF RADIO / TRANSPORTABLE SYSTEMS

A transportable, software-defined HF radio that scales from 1 W to 150 W, carrying secure long-range voice and data for special forces and remote advise and assist missions.

INNOVATION AT OUR CORE

BUILT FOR THE ADVISE AND ASSIST MISSION

Specialist support means little if the operator cannot reach it. The Sentry-H Portable Kit (SPK) brings a full software-defined HF radio into a single transportable case, so the connection travels with the operation even when no established network exists. With scalable power from 1 W to 150 W in 1 W steps, the SPK can accommodate discreet signatures or long-haul links, with no external amplifier or built-in batteries. Optimised for in-field use, the SPK deploys fast and moves easily around the world.

MORE INTEGRATED SOLUTIONS

NARROWBAND AND WIDEBAND IN ONE KIT

Equipment should serve more than one kind of mission. The Sentry-H Portable Kit is dual-use: paired with an end-user device running SprintChat or SprintNet, it carries secure email, file transfer, and chat over narrowband HF; paired with a laptop running INL waveforms, it opens up to 512 kHz of ultra-wideband performance. A single SPK carries legacy interoperability and modern secure data together, so it works alongside the systems already in service.

PROVEN RESILIENCE

RUGGED MIL-STD-810G FOR THE FIELD

Critical communications must survive the mission. The Sentry-H Portable Kit ships in a rugged, waterproof Pelican case built to a MIL-STD-810G design, running from any 10 V to 36 V power source. AES-256 and DES-56 COMSEC protect every voice and data path, while embedded GPS keeps position awareness live. Designed and built by Codan and field-proven with special forces in Remote Advice and Assist roles, the SPK is backed by DTC 24/7 support teams across 165+ countries.

MISSION OUTCOME

The Sentry-H Portable Kit puts sovereign, long-range HF communications into one transportable case that scales from 1 W to 150 W. Operators gain secure voice and data over narrowband or ultra-wideband HF, with TWELP and MELP digital voice, in a build made to move and survive in the toughest environments. From special forces reachback to maritime and unmanned operations, the Sentry-H Portable Kit performs where infrastructure ends.
