How the POYNTING OMNI-402 and Teltonika RUTX11 Delivered Reliable Internet Across Remote Adriatic Waters
Our client is a successful entrepreneur who works remotely from his boat while sailing along the Dalmatian coast in the Adriatic Sea. Combining business with leisure, he relies heavily on stable mobile internet for work, communication, and navigation during his journeys. However, the remote islands presented a serious challenge with poor or no mobile signal coverage, impacting his ability to stay connected.
This case study shows how the high-performance POYNTING OMNI-402 marine antenna paired with the Teltonika RUTX11 LTE router and supported by Masterline d.o.o. — distributor and technical expert — provided a reliable connectivity solution for the client’s demanding marine environment.

The process began with identifying the client’s connectivity needs while sailing remote Adriatic islands. It was clear that a durable, high-performance solution was necessary to handle weak and shifting signals. Next, the team selected the OMNI-402 antenna and Teltonika RUTX11 router as the best fit for marine use.
Installation involved securely mounting the OMNI-402 antenna on the boat’s mast to maximize signal reception from all directions. The antenna was then connected to the router inside the boat.Network setup included integrating SIM cards into the router and fine-tuning LTE settings to optimize signal strength and stability.
Extensive real-world testing was performed during sailing trips across multiple islands, confirming consistent internet availability and strong signal reception.Masterline d.o.o. provided ongoing support throughout this process, making any needed adjustments for smooth and reliable operation.
After implementing the solution, the client experienced:
This setup effectively transformed remote maritime zones from unreliable connectivity dead spots into fully connected work and leisure environments.
The client said:
“With the OMNI-402 antenna and the Teltonika RUTX11 router, I can now work from my boat without interruptions — even in places where I had no signal before.”
Reliable internet on the water is essential for safety, productivity, and peace of mind.
