Product Description

Features of the Nextivity CEL-FI GO G41 Smart Signal Booster

  • The most powerful carrier-grade cell phone signal booster in its class, providing up to 100 dB gain—hundreds of times more than competing home and small office boosters.
  • Amplifies your choice of Verizon, AT&T, T‑Mobile, UScellular, or GCI Alaska 5G and 4G/LTE. question mark inside a circle
  • Your choice of 1 to 4 ceiling-mounted dome antennas or flexible-mounting panel antennasquestion mark inside a circle
  • 15 dB of echo cancellation—three times as much as the GO G41’s predecessor, the GO G32—allows the booster to continue operating even when the outside and inside antennas are close enough to cause oscillation in other cell signal boosters. question mark inside a circle
  • Boosts voice, text, and data for multiple users simultaneously.
  • Configure and monitor your booster with the Nextivity WAVE app for smartphones.

The Nextivity CEL-FI GO G41 cell phone signal booster provides maximum gain for the carrier of your choice. Other home boosters amplify signals from all carriers simultaneously at a lower level of gain; the CEL-FI GO G41 amplifies one carrier at a time—Verizon, AT&T, T‑Mobile, UScellular, or GCI Alaska—and provides stronger signal gain on that carrier’s clearest frequencies.

This custom GO G41 kit, available only from Powerful Signal, includes both directional and omnidirectional outdoor antennas; you can use whichever antenna provides the booster with the best donor signal. It also includes your choice of up to four inside ceiling-mounted dome antennas or flex-mount panel antennas; choose the antenna type and configuration that best meets your needs.

The CEL-FI GO G41 helps you stay connected and experience fewer dropped calls, undelivered texts, and missed email messages. Keep your data moving faster in areas with weak cell service and in buildings that block outside cell signal.

Who is the Nextivity CEL-FI GO G41 Smart Signal Booster for?

  • Those who frequently experience dropped calls, undelivered texts, or slow cellular data speeds in homes, home offices, and small offices.
  • Homes and small offices in remote locations with weak cell service (new communities, rural areas, cabins, etc.).
  • Homes and small offices made with materials that block outside cell signal (metal, plaster, concrete, UV-coated windows, etc.).
  • Homes with basements, theater rooms, metal out-buildings, and other places where cell reception is poor.
  • Homes and small offices that need improved coverage for only one specific cellular carrier.

One to four inside antennas for maximum flexibility

Powerful Signal’s CEL-FI GO G41 system can be configured with one to four inside antennas to match your home’s configuration and meet your improved signal needs.

You’ll need access to an attic or crawlspace above the ceiling to pull cable and mount the dome antennas.

The panel antennas can be mounted on walls or ceilings. They also stand upright on flat surfaces.

Nextivity CEL-FI GO G41 Smart Signal Booster kit contents

The CEL-FI GO G41 is a complete kit, with everything you need to start getting the best signal.

A one-antenna CEL-FI GO G41 system will cover most homes of typical size. Homes that are long and narrow, have more than two floors, or have specific problem areas can use two, three, or four inside antennas to distribute the signal coverage. Connect one run of coax cable to the outside antenna (using the shortest length of cable possible) and one or more of the other runs to the inside antenna; use the barrel connector to attach two runs of cable together, if needed.

How it works

Nextivity’s CEL-FI GO G41 receives the outside cell signal, amplifies it, and rebroadcasts it inside your home or small office through one to four inside antennas. This allows you to stay connected in areas where cell service is poor or where building materials interfere with signals from the local cell tower.

Works with most major cellular carriers

The Nextivity CEL-FI GO G41 Smart Signal Booster system works with Verizon, AT&T, T‑Mobile, UScellular, and GCI Alaska 5G and 4G/LTE cellular bands. It does not work with other cellular networks.

The CEL-FI GO G41 Smart Signal Booster operates on two bands of cellular frequency simultaneously from a single carrier. It supports only one carrier at a time.

  • 700 MHz (SMH) bands 12, 13.
  • 850 MHz (Cellular 850) band 5.
  • 1700/2100 MHz (AWS) band 4.
  • 1900 MHz (PCS) bands 2, 25.

Which antennas should I choose?

This complete kit includes both an outdoor directional and omnidirectional antenna and gives you the choice of one to four indoor dome or panel antennas. Here are some general guidelines for choosing and using the right antennas.

Outside (donor) antenna:

  • The cylindrical Top Signal omnidirectional antenna works well in many situations. An omni antenna sends and receives signal to and from your carrier’s cell towers in all directions, and it doesn’t require any adjustment once it’s set up.
  • The wedge-shaped Top Signal directional antenna (LPDA) works best if your home has a reasonably clear line of sight to a specific cell tower that provides service for your cellular network. A directional antenna needs to be tuned (adjusted until it’s receiving the best signal), so setup is more involved than setting up an omni antenna.

Inside (broadcast) antenna:

  • The ceiling-mounted Top Signal EDGE dome antenna works best in many situations. It broadcasts downward and all around in a shape similar to a donut or an inner tube. It usually gives more broad, even coverage than a wall-mounted panel antenna and is less noticeable than a panel antenna. Installing a dome antenna does, however, require that you have access above the ceiling to pull cable and mount the antenna.
  • The wall-mounted Top Signal EDGE panel antenna broadcasts forward in a sideways teardrop shape. It’s a better option if you don’t have access above your ceiling or if you want to mount the antenna on the outside perimeter of the area you want to cover. It’s also a good option for long, narrow indoor areas.

If you’re uncertain which antennas will work best for you, please call us at 435-634-6800. Our technical support representatives will be happy to discuss your specific requirements and give you a recommendation based on years of professional experience.

How much area will the CEL-FI GO G41 cover?

The coverage area this Smart Signal Booster can provide depends on many factors, including:

  • Outside signal strength received by the donor antenna.
  • The outside antenna you use.
  • The length of coax cable between the outside antenna and the booster. (Always use the shortest cable possible for this run.)
  • The type of antennas you choose (dome or panel) and where you position them.
  • Inside building materials. (Cellular frequencies pass through wood framing and drywall more easily than through steel and concrete.)
  • The cellular frequencies used by the carrier. (Lower-frequency SMH and CLR signals travel farther than higher-frequency AWS and PCS signals.)

In general, the stronger the outside cell signal, the greater the interior broadcast distance.

Powerful Signal has has been designing and installing cellular amplification systems since 2007. Please call us at 435-634-6800 or contact us online, and we’ll be happy to calculate the coverage area this system will provide in your building and answer any other questions about this amplifier.
