Product Description

Features of the Marine Cel-Fi GO Cabin system

  • May be used while your vessel is underway or moored.
  • Boosts one carrier at a time for multiple users simultaneously. The Cel-Fi GO booster amplifies your choice of Verizon (5G/4G), AT&T, T‑Mobile, Sprint, UScellular, or GCI Alaska (5G/4G/3G). (Learn more about 5G compatibility.)
  • Unlike other mobile boosters, the Cel-Fi GO can be used while your vessel is moored or underway. The booster provides an industry-leading gain of up to 100 dB in stationary mode* and up to 65 dB in mobile mode; switch modes with the Cel-Fi WAVE app for smartphones.
  • Marine-grade exterior antenna with 20 feet of RG58 coax cable.
  • The inside desktop antenna rests on any flat surface and can be easily moved to where you need better signal in your boat.
  • The inside antenna connects to the booster with your choice of 5, 10, 15, 20, or 30 feet of 0.2″ (5 mm) coax cable. Choose the cable length that’s best for your needs.
  • Includes both 120-volt AC and 12-volt DC power supplies.*

* 100 dB stationary mode is available only when the Cel-Fi GO booster is powered by the 120V AC power supply.

The Marine Cel-Fi GO Cabin cell phone signal booster improves cellular reception for boats and vessels that are moored and are underway. Stay connected on lakes and rivers and in coastal waters. Experience faster 5G/4G data and fewer dropped calls, undelivered texts, and missed email messages.

The Marine Cel-Fi GO gives you maximum flexibility for getting better cell signal in your boat. Place the inside desktop antenna where you need signal most—the dining area, the helm, etc.—and move it as needed. This system includes your choice of length of thin, flexible LMR195 coax cable that makes moving the antenna quick and simple.

Motor yacht underway The Marine Cel-Fi GO works on boats that are underway, at anchor, or dockside.

Who is the Marine Cel-Fi GO Cabin system for?

When having a usable cell phone signal in your boat isn’t a luxury, it’s a critical necessity.

  • Mid-size vessels, such as cabin cruisers, motor yachts, trawlers, tugs, pilot boats, and fire boats.
  • Boaters who need improved cell signal while moored and while underway.
  • Boats that need better signal in 1 to 2 compartments, such as a wheelhouse, saloon, or cabin.
  • Vessels operating in remote waterways, where cell service is poor.
  • Government agencies (fish and wildlife services, harbor patrols, police and sheriff’s departments, etc.).
  • Anyone who needs the best, most reliable cell phone connectivity.

Get more features with the Cel-Fi WAVE app

With the Cel-Fi WAVE app for smartphones you can check your Cel-Fi GO booster’s status and change its settings:

  • Dashboard: An overview of the state of your Cel-Fi GO booster system, including the outside signal strength and quality and antenna separation.
  • Settings: Switch between mobile and stationary modes, change the default carrier, update your booster’s software, and more.
  • Advanced: Get detailed technical information for troubleshooting.

Do-it-yourself installation

You can install the Marine Cel-Fi GO Cabin system yourself; it does not require professional help.

  • You’ll need a standard-size 1-inch × 14 threaded marine mount for the omni marine antenna. (Powerful Signal offers a Shakespeare 4190 rail mount as an optional add‑on, above.)
  • Run the RG58 coax cable to the booster unit, securing the cable to the mast, tower, or hull.
  • Place the inside antenna on a flat surface of the compartment where you need improved signal.
  • Run the LMR195 coax cable from the inside antenna to the booster.
  • Attach the connectors on the cables to the antennas and the booster, then plug in the booster using the AC or DC power supply cables.
  • If the Cel-Fi WAVE app indicates that Antenna Separation poor, move the inside desktop antenna farther away from the outside marine antenna.
