KNL Radio

The KNL Radio is rack mountable and requires an included HF antenna (powered by a transformer), a cellular antenna, and a GPS antenna. All hardware is included in our monthly subscription.

We’ve built our radio to serve a number of use-cases, all while being simple, secure, and reliable to operate.

Technical Specifications

HF for Data Communications
Our R&D has greatly improved the speed and reliability of HF for data communications, giving each radio a two-way connection range of up to 10,000 kilometers.

Industrial Mesh Network
Each radio can act both as a base station (when in cellular range), and as an endpoint (when out at sea). The result is unmatched reliability and global access.
