  • 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 195 coax cable.

  • 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 195 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™ brand is a trademark of 3M.

Quick-release antenna for low-clearance passages

Many inland waterways have low minimum-clearance passages. RFI’s Q‑Fit® threaded quick-release connector provides fast, easy takedown and setup for low-clearance areas. The antenna attaches and detaches from its base in seconds.

LTE Marine Antenna RFI Quick-Release 82-Inch Whip 8.5 dBi 698–2700 MHz with Ferrule & Cable TS210902 quick-release connector RFI’s whip antenna includes a threaded quick-release ferrule that allows you to remove and reattach the antenna in seconds. (Click to enlarge.)
