Marine Coastal Cellular Signal Booster for Large Ships & Motor Yachts

Features of the Marine Coastal Cellular Signal Booster

• The most powerful cellular signal amplifier for multi-deck vessels, including motor yachts, naval support ships, research ships, feeder vessels, and other similar ships.
• Combines a cell signal booster designed for large buildings with your choice of antennas for the best possible signal while underway and while moored.
• Ample uplink power (24–25 dBm) for a stronger connection to the cell tower and better performance in areas with weak outside cellular signal.
• Built-in XDR (eXtended Dynamic Range) technology prevents overload and shutdown, no matter how strong the outside signal is.
• The cellular signal booster’s color LCD touchscreen displays the status and gain of each cellular band and allows you adjust its settings.
• Your choice of outside high-gain marine antenna. (Get help choosing the right antenna.)
• 29.5″ Poynting OMNI-493 UV‑stable ASA antenna with 6 to 9 dBi of gain.
• 81.9″ RFI CDQ7199 Q-Fit® fiberglass antenna with 4.5 to 8.5 dBi of gain and a quick-release feature for easy, fast setup and takedown.
• Your choice of four inside puck or panel antennas. (Get help choosing the right antenna.)
• Poynting PUCK-1 omnidirectional dome antenna with up to 7 dBi of gain and six mounting options.
• Top Signal EDGE directional panel antenna with 4.3 to 7.5 dBi of gain and four mounting options.
• Includes eight runs of pre-terminated low-loss 400-type coax cables in various lengths to connect the antennas to the cell signal booster.

The Marine Coastal Cellular Signal Booster improves cellular reception for ships and vessels that are moored and underway. Stay connected throughout your vessel while sailing in coastal waters, in harbors, at anchor, and while docked. Experience faster 5G/4G data and fewer dropped calls, undelivered texts, and missed email messages.

Your choice of high-gain marine antenna

The Marine Coastal Cellular Signal Booster includes an outside marine antenna for sending and receiving cell signal to and from cell towers.

29.5″ Poynting OMNI-493

The Poynting antenna connects to a 1″ × 14 thread marine mount (left) or to a 1½″‑2″ pole (right). (Click to enlarge.)

The Poynting OMNI-493 is the right choice if you need a shorter antenna or if you want the best reception for high-frequency cellular bands that have faster data rates. It has 7 dBi of gain on low-band cellular frequencies (617–960 MHz) and 8 to 9 dBi of gain on higher-band frequencies (1710–3800 MHz). Higher frequencies have a shorter range but offer faster data rates, so the Poynting OMNI-493 is the better option if faster data is more important for you than receiving signal at longer distances from cell towers.

The Poynting antenna attaches to a standard 1″ × 14 thread marine mount with an exit hole through which you can run a 1′ TS-195 jumper cable (included) and connect to a 400 coax cable that runs to the booster. The antenna also mounts to poles or posts 1½″ to 2″ in diameter.

81.9″ RFI CDQ7199

The RFI whip antenna is about 6′ 10″ tall. (Click to enlarge.)

The RFI CDQ7199 is the right choice if you want the best reception for low-frequency cellular bands that have a longer range. It has 8.5 dBi of gain on low-band cellular frequencies (617–960 MHz) and 4.5 to 5.5 dBi of gain on higher-band frequencies (1710–2700 MHz). Lower frequencies offer slower data rates but have a longer range, so the RFI CDQ7199 is the better option if receiving signal at longer distances from cell towers is more important for you than having faster data speeds.

The RFI antenna attaches to a standard 1″ × 14 thread marine mount. It includes RFI’s Q‑Fit® threaded quick-release connector for fast, easy takedown and setup for low minimum-clearance passages—the antenna attaches and detaches from its base in seconds. It includes 16.4′ of attached RG58 coax cable, which you may connect to the booster with an adapter (included) or attach to a 400-type coax cable to create a longer run.
