Product Description

Features of the Cel-Fi GO Fifth-Wheel Towed Vehicle system

  • Includes two sets of antennas and two power supplies. Use in your RV, motorhome, fifth wheel, or trailer and in your pickup truck or tow-behind car—just disconnect and move the booster for improved signal in both vehicles.
  • The Cel-Fi GO booster provides an industry-leading gain of up to 100 dB in your parked RV, fifth-wheel, or trailer and up to 65 dB in your car or pickup truck when underway. You can switch the booster between stationary and mobile modes with the Cel-Fi WAVE app for smartphones.
  • This booster amplifies 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.)
  • Wilson Electronics’s modular Drive OTR antenna gives you a choice of antenna mast lengths between 10.5″ and 41.5″. The Drive OTR antenna attaches to a ladder or other rail with a 3-way antenna mount (included) and includes 16 feet of coax cable.
  • Top Signal’s directional EDGE panel antenna stands upright on any flat surface. Move the antenna where you need improved cell signal inside your RV, fifth wheel, or trailer. Connect the antenna to the booster with your choice of 5, 10, 15, 20, or 30 feet of thin, flexible coax cable.
  • The magnet-mount antenna and a dashboard-mount antenna install in your pickup truck or tow-behind car. (If you have an aluminum-body truck, attach a steel disc to your cab roof to use the magnet-mount antenna.)
  • Includes a 120V AC power supply for use in your rig and a 12V DC power supply for use in your personal vehicle.

The Cel-Fi GO Fifth-Wheel Towed Vehicle cell phone signal booster system improves cellular reception inside RVs, motorhomes, fifth wheels, and trailers. Place the inside panel antenna where you need signal most—the dining area, the driver’s console tray, the bedroom, even outside—and move it as needed. This system includes your choice of between 5 and 30 feet of flexible LMR195 coax cable that makes moving the antenna quick and simple. With sufficient outside signal strength (−115 dBm RSRP or at least 1 bar), the Cel-Fi GO booster, OTR antenna, and panel antenna can improve signal across half of your rig or more.

This system also includes a separate set of antennas and a 12-volt power supply to install in your pickup or towed vehicle. Simply disconnect the Cel-Fi GO booster in one vehicle and reconnect it in the other. Use the Cel-Fi WAVE app to switch between stationary and mobile modes, depending on how you want to use the booster.

Whether you’re at an RV resort, a remote national park, or mountain getaway, the Cel-Fi GO Fifth-Wheel Towed Vehicle system will help you stay connected, with faster 5G/4G data and fewer dropped calls, fewer undelivered texts, and fewer missed email messages.

Who is the Cel-Fi GO Fifth-Wheel Towed Vehicle system for?

  • Class A motorhomes (30–45 feet long) with towed cars that need improved cell signal in both vehicles.
  • Fifth wheels, travel trailers, toy haulers, and other rigs towed by a pickup truck or SUV.
  • RVs and towables that need better signal throughout the rig.
  • Government agencies with RVs that serve as mobile command posts (police, disaster recovery, etc.).
  • Anyone who needs the best, most reliable cell phone connectivity in their RV or towable.
