Harness the power of Peplink HD4-MBX

At the heart of the Celldome is the best cellular router available,
proven the most reliable, not only yachting, but in a wide range of industries

16 High Gain Omni-directional Antennas

Promarine 5311 antennas ensures best range in any direction and are also 5G ready, covering the 3.4 – 3.8 GHz band

Short coax cables, terminated in ideal conditions

Not only do short, low loss cables ensure the best performance possible, they’re terminated and tested in a controlled environment meaning better performance and long term reliability

Easy to install

All of the technical install is done in our workshop, meaning the Celldome just needs an ethernet, power and grounding cable installed on site. Crew or shipyard can now install and still expect Ultimate Performance
