Product Description

Coastal Cruising Marine Cel-Fi GO G32 Cell Signal Booster with 82-Inch High-Gain Antenna Top Signal TS559113

Features of the Coastal Cruising Marine Cel-Fi GO G32 high‑gain antenna system

  • Combines the most powerful consumer cell signal booster with an 82″ high-gain marine whip antenna for the best possible signal while underway and while moored.
  • Boosts one carrier at a time for multiple users simultaneously. The Cel-Fi GO G32 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 G32 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.
  • RFI’s 81.9″ (208.0 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.) Cable extensions using low-loss 400 coax are also available at additional cost.
  • 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.) Connect the antenna to the booster with 5, 10, 15, 20, or 30 feet of thin, flexible 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 G32 booster is powered by the 120V AC power supply.

 LTE Marine Antenna RFI Quick-Release 82-Inch Whip 8.5 dBi 698–2700 MHz with Ferrule & Cable TS210902 quick-release connector The RFI whip antenna is 81.88″ (208 cm) tall, or about 6′ 10″. (Click to enlarge.)

The Marine Cel-Fi GO G32 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 82″ RFI Q-Fit® marine antenna provides 4.5 to 8.5 dBi of signal gain, sending stronger signal to the Cel-Fi GO booster for better inside cellular coverage and a stronger connection to the cell tower.

The inside Top Signal EDGE panel antenna can be placed where you need signal most—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. Choose your preferred length of thin, flexible LMR195 coax cable to connect the panel antenna to the booster.

Command® is a registered 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.)

Who is the Coastal Cruising Marine Cel-Fi GO G32 high‑gain antenna 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.
  • Houseboats.
  • Boaters who need improved cell signal while moored and while underway.
  • Boats that need better signal in one or two compartments, such as the 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.
Sailboat moored to an anchor bouy The Marine Cel-Fi GO G32 works on boats that are underway, at anchor, or dockside.

Get more features with the Cel-Fi WAVE app

With the Cel-Fi WAVE app for smartphones you can check your Cel-Fi GO G32 booster’s status and change its settings:

  • Dashboard: An overview of the state of your Cel-Fi GO G32 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 Coastal Cruising Marine Cel-Fi GO G32 high‑gain antenna 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. Use the FME-male/SMA-male adapter (included) to complete the connection to the booster.
    (If you use a 400 coax extension, the connection will be: RG58 cable → N‑female/FME‑male adapter → 400 coax → N‑female/SMA‑male RG58 jumper cable → 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.
  • Plug in the booster using the AC or DC power supply cables.
  • If the Cel-Fi WAVE app indicates that Antenna Separation poor, change the direction the inside panel antenna is pointing. (It should be facing away from outside antenna.)
