Better Cell Signal for Large Vessels Is Available!

Ships and large yachts have difficulty receiving cellular signal due to their steel hulls and long distances from cell towers. Powerful Signal offers large ship systems (LSS) that amplify and broadcast cell signal inside multi-deck commercial ships, workboats, military vessels, and large private yachts. These range in size from a small system for the bridge to a large, multi-deck system that covers your the entire vessel.

Large ship systems provide cellular reception in any or all parts of the ship, eliminating the need to go up on deck to make a phone call. With Powerful Signal’s LSS, you can get strong cell signal on the bridge, in the galley, crew quarters, work areas, and engine room.

Powerful Signal’s LSS cellular systems do not require a license fee and have no monthly charges.

Installation Diagram

“Thank you so much for the help getting this system ordered and across the finish line. Powered it on and just about everywhere on the boat we wanted to have signal now has 2 bars of 5G minimum, where it used to be no service. The crew is thankful, and it was cool to see members on phone calls on the mess deck. The system was fairly simple to install and I’m looking forward to seeing how it works in our home port of Astoria. Thank you again for all the help!”
