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.
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.
The Nextivity WAVE app for smartphones lets you check your CEL-FI GO G41 booster’s status and change its settings:
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.
All kits include:
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.
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.
