Frequently Asked Questions

We know, there’s a lot to take in! Here are answers to some of the questions we see most often.

The Cel-Fi GO G43 signal booster is able to support up to 3 carriers simultaneously. It can amplify cellular signals from AT&T, T-Mobile, and Verizon. This provides comprehensive cellular coverage for locations where multiple carriers may have poor service.

Due to regulations set by the Federal Communications Commission (FCC), Cel-Fi signal boosters are able to provide up to 100dB of total gain. The FCC limits most in-building and in-vehicle signal boosters to a maximum 70dB gain in order to prevent interference with nearby cell tower signals. At higher gains, boosters run the risk of re-amplifying and re-broadcasting tower transmissions at too strong a power level. However, Cel-Fi boosters are carefully engineered and FCC approved to maximize allowable gain up to 100dB.

No, the Cel-Fi GO G43 does not require professional installation. Waveform provides excellent resources to help customers complete a self-install. Our detailed user manual includes clear step-by-step instructions with illustrations to guide correct antenna placement and equipment setup. For additional assistance, we offer free lifetime support from our expert technicians. Customers can contact our friendly and knowledgeable support team via phone or email with any questions during or after the installation process. 

The Cel-Fi GO G43 has three donor antenna ports and two indoor antenna ports.

Yes, the donor antennas on the Cel-Fi GO G43 can be aimed separately. Since the booster is capable of amplifying signals from up to three different cellular networks simultaneously, it allows the outdoor donor antennas to each be pointed in optimal directions for independent carrier signals. Being able to aim donors individually helps ensure the strongest possible reception of each network.

The Cel-Fi GO G43 can cover a building up to 20,000 sq ft. You can utilize multiple G43 units in one building or upgrade to the QUATRA product line for larger buildings.
