CEL-FI GO X Smart Signal Booster System
CEL-FI GO X Smart Signal Booster System
Product Info
Product Info
The CEL-FI GO X System is our top recommended signal booster for homes, offices, and other buildings where the existing outside signal is 2 bars or less. The GO X is a single carrier system, which allows the GO X to have up to 100 dB of gain instead of being limited to only 70 dB of gain for multi-carrier systems. This extra power allows you to get more coverage even when the signal is weak.
Why the CEL-FI GO X?
- More boosting power than multi-carrier boosters for maximum coverage even with a weak outside signal.
- CEL-FI WAVE smartphone app makes it easy to monitor the system and troubleshoot any issues as necessary.
- NEMA 4 rated amplifier enclosure means the amplifier can be installed outdoors.
- Works wirelessly. No physical connection to your phone required.
- Supports multiple phones at the same time.
- Everything you need is included in the kit.
- Bonus: lightning protector kit & pole mount included.
- Fewer dropped calls
- Faster Internet data speeds
- Better voice quality
- Texts that send quickly
- Longer battery life
Your purchase is covered by our 60-day money-back guarantee, so you can try it risk-free, and our friendly, US-based technical support team is standing by to assist with anything you need. Your equipment is also covered by a 2-year manufacturer warranty, for extra peace of mind.
Recommended For
The CEL-FI GO X is our most-recommended booster for people with a weak (but usable) existing outside signal. If your signal is 50% or less when you’re outside (2 out of 4 bars, 3 out of 5 bars, etc), then the GO X will give you better performance and more coverage than a multi-carrier system.
The GO X is a single carrier system, so it only supports one carrier at a time. It works best for families or offices where everyone uses the same carrier, or where only one carrier has a weak signal inside. The GO X will support either Verizon, AT&T, or T-Mobile at a time, and the supported carrier can be changed at any time using the CEL-FI WAVE smartphone app.
The GO X configured for AT&T will support the modern 4G LTE and 5G networks and the older 3G and 4G HSPA+ networks, so any phone will be able to use the GO X.
The GO X configured for Verizon will only boost Verizon’s 4G LTE and 5G networks. All phones that support 4G LTE will get fast data speeds, but only phones that support VoLTE calling will be able to make and receive phone calls with the GO X. All iPhone 6 (released in 2014) and later iPhones will support VoLTE calling. For Android, search Google for your phone model and “VoLTE” to see if it is supported.
The GO X configured for T-Mobile will support 4G LTE and the older 3G and 4G HSPA+ networks, so any phone will be able to use the GO X. It does not currently support 5G from T-Mobile.
CEL-FI WAVE App
The GO X is one of the more intelligent amplifiers that we carry thanks to the companion CEL-FI WAVE app for iPhone and Android. The WAVE app allows you to do many things, including:
- Register the booster with your carrier, if necessary
- See how well the system is working and troubleshoot it if necessary
- Change from stationary mode with 100 dB of gain to mobile mode with 65 dB of gain.
- Change the carrier you want to boost
- Use the antenna position tool to aim an outdoor directional antenna
How it Works
The CEL-FI GO X starts outside with a directional outside antenna. This antenna is designed to be mounted to a pole that’s 2 inches in diameter or less, and we include a 20-inch tall aluminum j-pole with your kit. If you have an existing pole that extends above the roof of your house, you can use that as well.
The antenna picks up the existing outside signal and routes it over a 30 ft cable down to the amplifier which receives the signal and amplifies it. The signal is then sent to one or more inside antennas which rebroadcast the boosted signal throughout your space.
The entire process also works in reverse, so you get a strong and reliable connection back to your carrier.
For more information on cable lengths and included accessories, see the Kit Includes section at the bottom of the page. Different cable lengths are available for custom installations. Please contact us if you need to customize this kit.
Estimated Inside Coverage
The strength of your existing outside signal, measured in the location where you plan to mount the outside antenna, has a direct impact on the amount of inside coverage you'll get from a signal booster. The distance between the inside and outside antennas can also dramatically impact the size of the coverage area. The table below shows how much coverage you may get depending on your outside signal strength:
| Existing Outside Signal Strength | Estimated Inside Coverage | |||
|---|---|---|---|---|
| 1 Antenna | 2 Antennas | 3 Antennas | 4 Antennas | |
| Strong (5 Bars) | Up to 4,000 sq ft | Up to 7,500 sq ft | Up to 12,000 sq ft | Up to 15,000+ sq ft |
| Medium (3-4 Bars) | Up to 4,000 sq ft | Up to 7,500 sq ft | Up to 12,000 sq ft | Up to 15,000+ sq ft |
| Weak (1-2 Bars) | Up to 3,000 sq ft | Up to 4,500 sq ft | Not Recommended | Not Recommended |
| None (0 Bars) | No Coverage | |||
Please Note:
It is important to remember that there are many factors that impact the size of the inside coverage area, so actual results may vary from these estimates.
A Note About Bars on Your Phone
The bars on your phone take into account not just signal strength, but signal quality. The CEL-FI GO X can significantly increase the signal strength that your phone receives, but it’s very difficult to improve the signal quality. If you have a very poor quality outside signal, it’s possible that you’ll only get 1 or 2 bars inside with the booster, but the important thing is that you’ll be able to make calls and use data in places where you couldn’t before.
Will this Work for my Phone and Carrier?
The CEL-FI GO X is designed to boost only one carrier at a time. The booster can be reconfigured to change which carrier is boosted, so you’re not locked in to just one carrier, but it will only boost the carrier that it is configured for.

Please Note: The GO X will not work with any carrier other than Verizon, AT&T and T-Mobile. It will not work outside of the United States.
Outside Antenna - Yagi Directional
The yagi directional antenna is the outdoor antenna option that can handle the majority of situations that require a cell phone signal booster. It is directional, which means that it needs to be aimed towards the cell towers of the carrier(s) that you're trying to boost. Our guide on how to aim a directional antenna will walk you through the steps to do that.
The yagi directional antenna has 10 dB of gain and can cover about 75 degrees of the horizon in one direction, so any carrier towers that fall within that area will be boosted. The yagi antenna is not going to be a good option for scenarios where there are large hills, mountains, valleys, or canyon walls that prevent line of sight to the cell tower. If this is your situation, then please see below for better options.
Since a directional antenna can only cover a portion of the horizon, you may only be able to cover the carrier(s) with towers in the direction that the yagi antenna is pointing. The advantage is that because they are aimed, they're much more powerful so you'll get more coverage area inside of the building with a directional antenna.
Inside Antenna - Panel Antenna
Panel antennas are a type of directional indoor antenna. They can be mounted to a wall or to a ceiling. The signal comes out the front of the antenna so it must be mounted in a place where it is aimed at the area where you need coverage. A short pigtail cable comes out of the bottom of the antenna, so you do not need access behind a wall or ceiling to install a panel antenna.
In multi-story homes, panel antennas can be located in the attic pointing down to cover the floors below without any part of the system being visible.
The panel antenna has an average gain of 7 dBi on the low frequencies and 10 dBi on the high frequencies. This makes it more powerful than the dome antennas, but that is because it is a directional antenna, so it sends all of its signal in one direction instead of all directions.
