Product Description

Features of the Nextivity CEL-FI GO G32 Class B/Class C high‑gain antenna system

  • Combines the most powerful consumer cell signal booster with a high-gain whip antenna for the best possible signal in your motorhome or van.
  • Boosts one carrier at a time for multiple users simultaneously. The CEL-FI GO G32 booster amplifies your choice of Verizon, AT&T, T‑Mobile, UScellular, or GCI Alaska 5G and 4G/LTE. Works only within the United States. (Learn more about 5G compatibility.)
  • This complete kit features your choice of three mounting options for the high-gain outside 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 provides an industry-leading gain of up to 100 dB in Stationary mode when you’re parked and up to 65 dB in Mobile mode when you’re underway; switch modes with the Nextivity WAVE app for smartphones. Boosts one carrier at a time for multiple users simultaneously; choose from five major carriers; switch carriers at any time.
  • RFI’s 38.2″ (90.7 cm) fiberglass OTR antenna provides 4.5 to 6.5 dBi of signal gain and includes 16.4′ (5.0 m) of RG58 coax cable and a quick-release feature for easy, fast setup and takedown.
  • Top Signal’s directional EDGE panel antenna stands upright on any flat surface and connects to the booster with 15 feet of thin, flexible coax cable. Move the antenna where you need improved cell signal inside your RV, fifth wheel, trailer, or towable.
  • Includes a 120V AC power supply.

With sufficient outside signal strength (−115 dBm RSRP or about 1 bar), the CEL-FI GO G32 system can improve signal throughout your motorhome or van. Less outside signal will reduce the total coverage amount but you will still be able to call, text, and use cellular data closer to the inside antenna (as long as outside signal isn’t effectively zero).

  • Class C motorhomes (20–30 feet long).
  • Class B adventure vans, including the Mercedes Sprinter, Ford Transit, Dodge Promaster, Unimog, Unicat, Revel 4×4, Storyteller Overland, Adventure Truck XT, Roadtrek, Sportsmobile, and more.
  • 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 motorhome, van, or similar RV.
