Signal Booster Manuals & User Guides

Signal Booster is a provider of cellular connectivity solutions, specializing in devices that amplify weak mobile usage signals for improved performance. The brand offers a range of products, including the advanced Cel-Fi GO X Smart Signal Booster System, designed to eliminate dropped calls and increase data speeds for carriers such as AT&T, Verizon, T-Mobile, and Sprint.

Their systems generally function by capturing an existing outside signal via a donor antenna, amplifying it through a booster unit, and redistributing it indoors. Solutions are available for various environments, from residential homes and remote rural areas to large enterprise offices and fleet vehicles.

• How does the Cel-Fi GO X Signal Booster work?

  The Cel-Fi GO X uses three core components: an outside donor antenna to capture signal, an amplifier to boost the signal gain (up to 100 dB), and an inside antenna to broadcast the improved signal within the building.

• What carriers does the Signal Booster support?

  Most Signal Booster systems, including the Cel-Fi GO X, are compatible with major US carriers such as AT&T, Verizon, T-Mobile, Sprint, and US Cellular. Users typically select their carrier via a companion app like Cel-Fi WAVE.

• What is antenna isolation?

  Isolation is the separation required between the outdoor (donor) and indoor (server) antennas to prevent oscillation or feedback. Adequate vertical or horizontal distance is necessary for the system to function at full power.

• Will a signal booster work if I have no signal at all?

  No. Signal boosters require at least some existing signal to amplify. If there is absolutely no reception (dead zone) at the location of the outdoor antenna, the system cannot create a signal from nothing.
