The Cel-Fi GO X is an in-building cell signal booster that provides maximum gain for the carrier of your choice. Other home boosters amplify signals from all carriers simultaneously with lower signal gain; the Cel-Fi GO X amplifies one carrier at a time—your choice of Verizon, AT&T, T‑Mobile, Sprint, U.S. Cellular, or GCI Alaska—and provides stronger signal gain on that carrier’s best frequencies.
The Cel-Fi GO X 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 X system can be configured with one to four inside antennas to match your home’s configuration and meet your improved signal needs:
The Cel-Fi WAVE app for smartphones lets you check your Cel-Fi GO booster’s status and change its settings:
We offer the Cel-Fi GO X in four configurations that have everything you need to start getting the best signal in your home. Choose your preferred configuration from the drop-down list at the top of this page.
A one-antenna Cel-Fi GO X system will cover most homes of typical size. The different cable lengths in this kit will give you the maximum flexibility in setting up your GO X. Connect one length of cable to the outside antenna and one or two of the other lengths to the inside antenna. Use the barrel connector to attach two lengths of cable together, if necessary, always remembering to use the shortest lengths of cable possible.
A two-antenna Cel-Fi GO X system will cover most large homes. It’s also a good solution if your house has two specific problem areas you want to fix. Like the one-antenna solution, this kit includes different lengths coax cable and a barrel connector so you can use exactly the right amount of cable. (Adequate outside signal is needed to split signal two ways.)
A three- or four-antenna Cel-Fi GO X system is designed for the largest homes. It also works well in small offices in which all cellular devices are using the same carrier. (Strong outside signal is required to split signal three or four ways.)
Using Nextivity’s IntelliBoost signal processing, the Cel-Fi GO X 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.
This Cel-Fi GO X Smart Signal Booster system works with Verizon 5G/4G LTE cellular bands and AT&T, T‑Mobile, Sprint, U.S. Cellular, and GCI Alaska 5G/4G LTE/3G cellular bands. It does not work with other cellular networks, and it does not boost Verizon 3G.
The Cel-Fi GO X operates on two cellular bands simultaneously from a single carrier. It will support only one carrier at a time.
