More Coverage
The Cel-Fi GO-X is a three-part cellular repeater system featuring an outside yagi antenna, +100 dB amplifier, and inside dome or panel antenna for coverage up to 15,000 sq ft. While open spaces (like a warehouse) can get great 4G coverage with one inside antenna, buildings with many rooms, thick walls, and/or multiple floors may need 2 to 4 antennas to get reliable coverage.
With the downloaded Cel-Fi Wave App, the Cel-Fi GO-X can also be used in a stationary vehicle with additional accessories. Tough NEMA 4-rated design allows for outdoor installation and is weather-resistant against water, dust, and dirt.
More Power
Unlike multi-carrier signal boosters with a limit of +70 dB, Cel-Fi’s single-carrier solution boosts signal up to +100 dB for a difference of +30 dB or up to 1000x more power compared to multi-carrier boosters.
Better Monitoring
The free Cel-Fi Wave App allows for easy installation and monitoring for your 4G signal booster. It also allows for carrier-switching to boost AT&T, Verizon, T-Mobile, or US Cellular for a single carrier at a time.
Cel-Fi's mobile app also allows you to connect to the device over bluetooth and see detailed diagnostic information, including measures of signal strength (RSRP), gain, and signal quality (SINR).

FCC NOTICE:
This is a CONSUMER device. BEFORE USE, you MUST REGISTER THIS DEVICE with your wireless provider and have your provider's consent. Most wireless providers consent to the use of signal boosters. Some providers may not consent to the use of this device on their network. If you are unsure, contact your provider. You MUST operate this device with approved antennas and cables as specified by the manufacturer. Antennas MUST be installed at least 20 cm (8 inches) from any person. You MUST cease operating this device immediately if requested by FCC or a licensed wireless service provider.
Installation
Installing any consumer signal booster setup is fairly simple, but can be a pain. The results, however, are worth it.
- Install Outside Antenna.
- Connect to the Amplifier.
- Install Inside Antenna.
- Connect all with cables.
- Power on.
You’ll need some general handyman skills but nothing too specialized. If you prefer having someone else do the job, you can also contact your local general contractor, electrician, or anyone who’s installed a satellite TV dish.
- Find The Best Outside Signal: Begin by finding the best signal outside your house. This is done by walking around the perimeter of your home and either using the number of bars on your phone (ok method), smartphone apps (good method), or Field Test Mode (great method) to find the best location. Pro tip: Locating the side of your home getting the best signal is the MOST CRUCIAL step of the installation process.
- Install Yagi Antenna: The area with the best signal is where you will mount the yagi antenna. Place the antenna as high up as possible, ideally on the roof, although the fascia or gable is acceptable. It’s important that the outside antenna should be on or near the edge of the roof pointing away from the house to the cell tower and NOT pointing across the roof since it may cause interference with the inside antenna. Point the yagi antenna at your nearest cell tower.
- Connect to Amplifier: Once the yagi antenna is mounted, connect the included RG-6 cable to the yagi antenna and to the “outside antenna” port on the amplifier. Some run cable into the attic, others prefer using the window-entry cable. It’s all a matter of preference and aesthetics and where you want to locate the amplifier. Pro tip: The amplifier does all the heavy lifting for boosting signal and will get warm. Keep it in a well-ventilated area.
- Install Inside Antenna: Once the cable is connected to the “Outside Antenna” port of the amplifier, do the same for the “Inside Antenna” port. Some prefer having the antenna mounted on the ceiling, others prefer the wall. Again, it’s all a matter of preference, and use case. If you have a panel antenna, they generally perform best on the wall, and if you have a dome antenna, they usually perform best on the ceiling. If you have multiple antennas, you will need to use a splitter to divide the cable runs, and then place each antenna where you’d like them. Pro tip: Having enough separation between the two antennas prevents oscillation. Make sure there is at least 20 feet vertical or 50 feet horizontal distance between the two.
- Power on: Plug in the power supply to the Amplifier and to the wall outlet. The amplifier will sync up and if you see all green lights, then green means GO! Check to see near the inside antenna how much better signal you’re getting. Pro tip: Any post-installation adjustments like relocating the Omni Antenna will require rebooting the amplifier. Simply unplug the power supply for 5-10 seconds and replug to reboot the system.
