Product Description

Features of the Cel-Fi GO G32 OTR high‑gain antenna system

  • Combines the most powerful consumer cell signal booster with a high-gain whip antenna for the best possible signal on the road.
  • The Cel-Fi GO G32 booster provides up to 65 dB of signal gain, over 30 times the gain of competing mobile boosters.
  • 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.)
  • RFI’s 38.2″ (90.7 cm) fiberglass OTR antenna includes 16.4′ (5.0 m) of RG58 coax cable and a quick-release feature for easy, fast setup and takedown. (Learn more.)
  • This complete kit features your choice of three mounting options for the RFI antenna. (See photo gallery, below.)
  • Standard: The 2½″ rail mount secures to rails and brackets.
  • Optional upgrade #1: The fold-down “bull bar” mount lays the antenna flat instantly with a spring‑loaded pin.
  • Optional upgrade #2: The MagMAX 3X magnet mount firmly attaches to steel roofs.
  • The Cel-Fi GO G32 booster is NEMA 4 rated for protection against dirt and dust, rain, snow, splashing water, and other hazards. It’s an excellent solution for vehicles that operate in harsh or wet environments.
  • Configure and monitor your booster with the Cel‑Fi WAVE app for smartphones.

The Cel-Fi GO G32 mobile cell signal booster provides maximum gain for the carrier of your choice (Verizon, AT&T, T‑Mobile, Sprint, UScellular, or GCI Alaska). The GO G32 also has more downlink power than any other mobile booster for the greatest amount of coverage area inside your truck or other vehicle.

The 38″ RFI Q-Fit® OTR antenna provides 4.5 to 6.5 dBi of signal gain, sending stronger signal to the Cel-Fi GO G32 booster so you can stay connected, experience fewer dropped calls and missed messages, and have more reliable access to navigation and entertainment apps on your smartphone.

Who is the Cel-Fi GO G32 OTR high‑gain antenna system for?

  • OTR truckers and drivers of other CMVs.
  • Off-road recreational drivers.
  • Drivers who live or work in rural and remote areas, where available cell signal is weak.
  • Field service technicians (oil, gas, agriculture, etc.).
  • Government agencies (Forest Service, executive and legislative staff, military, etc.).
  • Emergency responders (police, sheriff, fire, EMT, etc.).
  • Vehicles that operate in wet, dusty, or other severe conditions.
  • Vehicles that need improved coverage for only one specific cellular carrier.

Do-it-yourself installation

Installing the Cel-Fi GO G32 high‑gain antenna system does not require professional help; you can do it yourself in about 30 minutes.

  • If you use the 2½″ mount or bull bar mount: Attach the mount to a rail or bracket in a location that will provide the whip antenna with the clearest 360° field of view.
  • If you use the optional MagMAX 3X mount: Secure this mount to a steel surface with a flat edge facing forward, into the wind stream. (See this photo.) Do not mount it with a pointed end facing forward. The whip antenna should have the clearest 360° field of view possible.
  • Thread the cable connected to the whip antenna’s spring mount through the hole on the rail or MagMAX 3X mount. Secure the spring mount to the rail or MagMAX mount from the bottom with the jam nut (included).
  • Run the RG58 coax cable inside to the booster unit. If you run the cable through a door, thread it through and behind the doorway’s weatherstripping. Securing the cable where needed to keep it from flailing in the wind. Use the FME-male/SMA-male adapter (included) to complete the connection to the booster.
  • Adhere the server (inside) antenna as close as possible to where you keep your phone while driving. For example, if you dock your phone in a cradle on the dashboard, the server antenna should be mounted to the dashboard right behind the cradle. (The closer the server antenna is to the phone, the more likely you are to receive improved signal when outside reception is very weak.)
  • Run the RG174 coax cable from the server antenna to the booster.
  • Plug in the booster using the DC power supply cables.
  • Use the Cel‑Fi WAVE smartphone app to check your signal strength, boost level, and antenna separation.

How it works

Using Nextivity’s IntelliBoost signal processing, the Cel-Fi GO G32 receives the outside cell signal, amplifies it, and rebroadcasts it inside your vehicle, allowing you to travel farther from cell towers and still stay connected.

Works with most major cellular carriers

This Cel-Fi GO G32 M Smart Signal Booster system works with Verizon 5G/4G LTE cellular bands and AT&T, T‑Mobile, Sprint, UScellular, and GCI Alaska 5G/4G LTE/3G cellular bands. It does not work with other cellular networks, and it does not boost Verizon 3G.

The Cel-Fi GO G32 M operates on two cellular bands simultaneously from a single carrier. It will support only one carrier at a time.
