The Codan Sentry-H™ series radios are the most intuitive, reliable and advanced radios we’ve ever built.

Sentry’s clear and dependable High Frequency (HF) voice and data communications means you have the confidence to communicate anywhere and anytime without the need for existing infrastructure, enabling true long range digital radio communications.

A true software-defined radio (SDR), Sentry delivers new capabilities to the radio through software upgrades so you’ll always have access to tomorrow’s features today. No matter what your communication scenario, Codan has you covered with Sentry’s compact mobile and base station solutions.

With Ethernet and USB connectivity, a large high-resolution colour display, and multi-language user interface — combined with legendary Codan performance, reliability and support — the Sentry smart radio is the new standard for HF tactical communications and your solution for long range digital radio.



Affordable and Intuitive Tactical Communications

At Codan we understand it’s tough today to afford a tactical High Frequency (HF) radio system that has all the features you desire, without compromising on essentials like durability and security. That’s why we’ve created the Codan Sentry-H Software-Defined Radio (SDR) with next generation Digital Voice, 3G ALE and Frequency Hopping. It’s the most robust and intuitive high-power SDR radio we’ve ever built for voice and data communications.
