This system is a three-carrier CEL-FI solution that provides up to 100 dB of signal gain, giving you the strongest carrier-preapproved cellular booster available with coverage for all three major cellular networks with no licensing or carrier contracts needed.
With strong outside signal (−95 dBm RSRP or greater), the CEL-FI GO G41 booster can provide up to 15,000 square feet of indoor cellular coverage. Multiple indoor antennas can distribute that coverage throughout your building, if you need several individual spots of coverage.
CEL-FI GO G41 technology is fully automatic and does not require any adjustment. At power-up, each amplifier analyzes its assigned carrier network to determine signal strength and quality, then it selects the best cellular band for that carrier.
The CEL-FI GO G41 three-carrier cell phone signal booster system sends and receives signal to and from cell towers in the local area. Because those towers are often in different directions from your building’s location, this system offers two outdoor antenna options:
Targeted mode uses three directional antennas that are each pointed at a specific cell tower—one for Verizon, one for AT&T/FirstNet, and one for T-Mobile. With three individually targeted directional antennas, each GO G41 amplifier will receive more signal (higher antenna gain) with less noise. This setup requires you to run three separate coax cables from the amplifier box to the antennas on the roof.
Omni mode uses a single run of coax cable from the amplifier box to the roof, where it connects to a high-gain omnidirectional antenna that sends and receives signal to and from all cell towers in all directions. This setup is easier to install than targeted mode; however, antenna gain is lower and noise is greater, reducing the indoor coverage area and signal quality the amplifiers can provide.
The Nextivity WAVE app for smartphones lets you check your CEL-FI GO G41 boosters’ status and change their settings:
The CEL-FI GO G41 three-carrier system includes TS-400 coax cables to connect the amplifiers to the inside antenna(s). If your building requires fire-rated cable in plenum spaces, please ask us about upgrading to half-inch plenum air coax. Plenum cable fully meets state and federal building codes.
Plenum cable also has nearly half the signal loss per foot of cable compared to TS-400 coax cable, providing stronger signal from your GO G41 multicarrier system and a wider indoor coverage area.
(Plenum air cable is available at additional cost. Call Powerful Signal at 435-634-6800 for details.)
In a large building, office, or warehouse, you’ll get the best results and performance from a CEL-FI GO G41 three-carrier system with a custom design and professional installation.
Working with your floor plans, Powerful Signal’s design engineers will create design specifications that will allow you to use the fewest number of components to get the maximum amount of cellular coverage inside your building.
Powerful Signal’s professional installer will have knowledge of local building codes and the proper tools and experience to make sure your system is set up and configured correctly.

The CEL-FI GO G41 three-carrier system can be self-installed if you are familiar with cellular amplification equipment. We’ll be happy to advise you on the best placement of antennas or provide a custom, turnkey solution. If you purchase this system as a standalone product, it includes the following components:
1-antenna systems also include:
2-antenna systems also include:
3-antenna systems also include:
4-antenna systems also include:
Nextivity’s CEL-FI GO G41 receives the outside cell signal, amplifies it, and rebroadcasts it inside your building 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.
The Nextivity CEL-FI GO G41 booster works with all three major cellular networks:
The three CEL-FI GO G41 amplifiers are each assigned to an individual carrier. Each amplifier analyzes the qualify of its carrier’s signal and chooses the two highest-quality channels within the available bands of cellular frequency.
This system includes one to four dome antennas that each broadcast improved cellular signal in a shape similar to a donut or an inner tube. The radius of coverage depends on many factors, including:
In general, the stronger the outside cell signal, the greater the interior broadcast distance.
With strong outside cell signal (−95 dBm RSRP or greater), the CEL-FI GO G41 three-carrier systems can cover up to 15,000 square feet of indoor building space with 700 MHz signal. With weak outside cell signal (−115 dBm RSRP), it may cover 2,500 square feet of indoor space or less.
Powerful Signal has over a decade of experience designing and installing cellular amplification systems.
