Welcome, Linus Tech Tips fans!

Hi! We're Waveform, the signal specialists.

In the last 14 years, we've helped tens of thousands of customers achieve blazing fast data rates and eliminate frustrating dropped calls.

We love nerding out about cell signal, and we specialize in finding the right solution for every unique situation.

Welcome to Waveform. We're the leaders in boosting cell signal in buildings, vehicles, and for 4G/5G routers. We’re a small team, but we really care about helping you get the best results.

There are hundreds of different cell phone signal boosters on the market and it can be hard to tell them apart.

But not all signal boosters are the same.

We've spent decades testing, installing, and supporting them, so we'll help you find the right solution to your signal problems.

Pro tip: Before buying a booster it's helpful to test your cell signal to understand exactly what you're working with. You can read more about how to test your cell signal on Android and iOS devices in this guide.

Some of Our Favorite Signal Boosters

Cel-Fi GO G41: The only 100 dB, Consumer-Grade Signal Booster

The Cel-Fi GO G41 is the smaller sibling of the Cel-Fi Quatra system which Linus installed in his home. Being a digital booster, like the Quatra, it brings the same tech to the table, in a simpler and more affordable package to make it suitable for most homes.

It isn't cheap, but it's still excellent value. Thanks to its 100 dB gain, the GO performs better than boosters that cost thousands of dollars more, and it will cover thousands of square feet even if your outdoor signal is quite weak.

Our Other Recommendations

There's no silver bullet in boosting cell signal, so the Go X might not always be the right solution.

We've found that many people looking for boosters are actually looking for the fastest possible data speeds for home broadband, with a hotspot or LTE router. If this sounds like you, check out our MIMO External Antenna Kits.

Need a cell signal booster that comes with installation? If so, the weBoost Installed Home Complete might be the right choice. Your Home Complete will include an installation card that allows you to schedule installation, often as soon as the next day.

If you're hoping to cover more than a few hundred square feet, this booster will need signal strength (RSRP) outdoors that is at least -80 dBm. If you have an Android phone handy, take signal measurements outside to help determine it's coverage.

Of course, a list of the best signal boosters wouldn't be complete without the Cel-Fi Quatra - the booster you saw Linus and Jake install.

It's almost always overkill for most homes, and it starts at a higher price point than the systems listed above. That said, here are just a few things that we've come to love about the Quatra line-up:

• Allows use of ethernet cables to distribute signal instead of coax.
• Offers 100 dB gain for AT&T, Verizon, and T-Mobile.
• Robust cloud-based monitoring and alarming allows for enterprise-grade SLAs.

Top of the line for high end installations

Cel-Fi QUATRA 2000

If you're deploying in a home or office that's larger than 5,000 square feet, this is the booster to beat. While it's relatively expensive, the performance of the Quatra 2000 is unmatched.

Because the Quatra needs to be sold as part of a custom-designed solution, you'll need to reach out to us and talk to one of our signal specialists before buying, so that we can design a custom system for you.
