Product Description

Features of the Marine SureCall Fusion2Go 3.0 high‑gain antenna system

  • Use in your boat and in your car, truck, or SUV with two sets of antennas and two power supplies (AC and DC)—just disconnect and move the booster for improved signal in both.
  • Best price‑for‑performance ratio of any mobile booster.
  • Excellent 5G/4G LTE/3G gain and uplink power for all major U.S. and Canadian cellular networks. (Learn more about 5G compatibility.)
  • RFI’s 38.2″ (90.7 cm) fiberglass marine antenna includes 16.4′ (5.0 m) of RG58 coax cable and a 1″ × 14‑thread ferrule that attaches to standard marine mounts. This antenna also has a quick-release feature for easy, fast setup and takedown. (Learn more.)
  • Top Signal’s high-performance directional EDGE panel antenna mounts flush to walls; it also stands upright on any flat surface and can be moved about the boat. (Learn more.) This antenna connects to the booster with 10 feet of thin, flexible LMR195 coax cable.
  • Provides up to 10 feet of improved signal coverage from the inside antenna.
  • Boosts voice, text, and data.
  • Boosts cell signal for multiple users simultaneously.
Motor yacht underway The Marine SureCall Fusion2Go 3.0 works on boats that are underway, at anchor, or dockside.

The SureCall Fusion2Go 3.0 cell phone signal booster provides excellent uplink power for better cellular reception on the water and on the road. The Fusion2Go has over 2½ times the uplink power of other mobile boosters in its class.

This marine kit adds the 38″ RFI Q-Fit® marine antenna that provides 4.5 to 6.5 dBi of signal gain; this antenna sends stronger signal to the Fusion2Go booster for better inside cellular coverage.

The inside Top Signal EDGE panel antenna can be placed where you need signal—the dining area, the helm, etc.—and moved as needed. You can also mount the EDGE panel antenna on a wall or ceiling with the mounting bracket (included) or with Command® Strips or similar adhesives (purchased separately). Ten feet of thin, flexible LMR195 coax cable connects the panel antenna to the booster.

This kit also includes a second set of antennas and a separate power supply so you can also use the Fusion2Go booster in a car, pickup truck, or SUV.

Command® is a registered trademark of 3M.

Who is the Marine SureCall Fusion2Go 3.0 for?

When you need the best cell phone signal in your boat at the best possible price.

  • Boaters who need improved cell signal while underway.
  • Boats that need better signal in a specific area, such as around the helm or at a dining table.
  • Boats that need amplified signal for multiple cellular carriers simultaneously.
  • Vessels that are used in remote waterways, where cell service is poor.
  • Government agencies (fish and wildlife service, harbor patrol, police or sheriff’s department, etc.).
  • Anyone who needs the best, most reliable cell phone connectivity on the water.

Do-it-yourself installation

You can install the Marine SureCall Fusion2Go 3.0 kit 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. Hand-tighten the FME-female connector on the cable to the FME-male connector on the booster.
  • Place the inside antenna on a flat surface or mount it on a bulkhead in the compartment where you need improved signal.
  • Run the LMR195 coax cable from the inside antenna to the booster. Use the included adapters to attach the cable to the FME connector on the booster and N connector on the panel antenna.
  • Plug in the booster using the AC or DC power supply cables.
  • If the booster’s status light is blinking red, change the direction the inside panel antenna is pointing. (It should be facing away from outside antenna.)
