The Best AT&T Boosters
For Homes & Small Offices

Best Overall


The best 4G and 5G AT&T signal booster for homes & offices, by a distance


The only booster with 100 dB gain

Unmatched coverage and data rates, even when signal outdoors is weak

Advanced configuration via iOS/Android apps that show signal metrics


Slightly more complicated than other boosters to install

It isn't cheap, but you're paying for better performance, and it shows


  • If you don't mind spending a little bit more, the Cel-Fi GO X is simply the best booster on the market today.

  • The GO X is the only booster with 100 dB gain. This is huge - the GO X will cover thousands of square feet even if your outdoor signal is quite weak.

  • An excellent iOS and Android app shows advanced diagnostics, which help with aiming the outdoor antenna

Before you buy:

  • Verify that you have "usable" signal outdoors.

    Even with all its gain, you need to have at least 1 bar of reliable 4G LTE signal outside for the GO X to latch onto.

  • In December 2023, CEL-FI released another GO product called the CEL-FI GO G41. The GO G41 doesn’t differ much from the current G32, though CEL-FI intends to upgrade it via firmware updates in the future. It’s meaningfully more expensive than the GO X G32 and we don’t feel the extra benefits are worth the higher price point at this time.

The Details

The GO X is our favorite AT&T booster on the market today.

While it's considerably more expensive than some of the other devices out there, we think it's worth paying a little extra.

Here's why:

The FCC allows two classes of signal boosters to be sold in the US:

  • Broadband boosters that amplify the signal of every carrier equally.
  • Carrier-specific boosters that amplify the signal of just one carrier at a time.

Broadband boosters are only allowed around 65 dB of gain. But Cel-Fi's GO X is a carrier-specific booster, which means it can amplify signal by 100 dB.

An extra 35 dB might not seem like much, but it makes a huge difference. Decibels are a "logarithmic scale" - so 35 dB is 1000x more amplification.

To give an example: let's say you have a decent, -90 dBm RSRP signal outside. With a 65 dB booster, your output power will be -25 dBm, which is 0.003 milliwatts. With a 100 dB booster like the GO X, your output power is 10 dBm, which is 10 milliwatts.

You're going to see a much bigger coverage area and much faster data rates with the GO X than with almost any booster out there.

The benefits don't just end there, though. The GO is also the only signal booster that actively demodulates 4G and 5G signals to tell you the signal strength and quality it's receiving. This allows you to dial in the outdoor antenna to get the best signal quality possible.

While the GO X can only boost one carrier at a time, you can toggle at any time between boosting AT&T, Verizon, T-Mobile, and US Cellular using the iOS and Android app.

Installation Included

weBoost Installed Home Complete

Not so handy? This booster kit includes nationwide installation


Includes nationwide installation by the team at Ontech Smart Services

Aesthetically pleasing indoor antenna

Works with multiple carriers simultaneously


Limited coverage area if outdoor signal is weak

Quality of installation depends on local technician

Kits aren't configurable to include multiple indoor antennas.


  • Does the idea of having someone else installing your booster sound appealing? If so, the weBoost Installed Home Complete might be a good choice!

  • This is a broadband booster, so it'll work best if you have relatively strong signal outdoors - at least 2 or 3 bars.

  • Note, this device can only be installed in homes. For offices, look at the weBoost Installed Office 200.

Before you buy:

  • If you have an Android phone handy, take signal measurements outside first. This booster will work best if your signal strength (RSRP) outdoors is at least -80 dBm.

The Details

weBoost has partnered with OnTech Smart Services to offer something truly unique: nationwide installs in any home.

The weBoost Installed Home Complete ships with an "installation card" that allows you to book your installation online. Install slots are often available the very next day.

OnTech's installers are armed with one of the best signal meters available on the market today: the Cell Linq Pro. Once they arrive at your home they use the Cell Linq Pro to help aim the outdoor antenna.

The Home Complete kit doesn't actually include any cables. Instead, the Ontech installers cut and crimp RG6 coax that they keep on their trucks to complete the installation.

All this makes for a super-simple installation: and if you're not handy, it may be the right choice for you.

The weBoost Home Complete isn't our favorite booster, mostly because it's a broadband amplifier that's limited by FCC rules to 70 dB gain. And the RG6 cable that Ontech installer's use isn't the best quality cable - it adds quite a bit of loss on longer runs. These two facts mean that the system won't cover your whole home unless your outdoor signal is quite strong. And unfortunately, weBoost won't allow you to customize the kit to add any additional antennas.

If the idea of running coax in your home has you sweating, the weBoost Home Installed Complete is worth considering. If you're unhappy with the results you're seeing, you can still return the kit and get a full refund. The only caveat to be aware of is that weBoost and OnTech won't patch the holes that they've made in your walls or the exterior of your home.

Budget Choice

SureCall Fusion4Home with Panel/Yagi Antennas

On a budget? The Fusion4Home is a solid mid-range booster


Works well if outdoor signal is strong or intended coverage area is small

Directional outdoor antenna allows optimizing signal quality

Ability to manually shut off frequency bands via switches on device


Limited coverage area if outdoor signal is weak

Manual can be slightly confusing

Uses different cables and connectors on the indoor and outdoor antennas


  • We think this version of the Fusion4Home – which includes a directional outdoor antenna – is the best device available if you're trying to minimize your spend.

  • However, temper your expectations: unless you have quite a strong signal outdoors, or you're looking to cover a small area, performance will be limited.

Before you buy:

  • Like all boosters, the Fusion4Home will only work if you have usable signal outdoors for the unit to amplify. Check your signal before buying.

  • Need to cover more than 500 sq ft? If so, you'll need strong signal (at least 2-3 bars, or -80 dBm RSRP if you're on Android and can measure your signal strength).

The Details

The Fusion4Home is the lowest-cost AT&T booster that we recommend using.

It covers all 5 bands authorized by the FCC, and includes a directional outdoor antenna - which allows you to aim your outdoor antenna and get the best AT&T signal into the system possible.

The Fusion4Home is a "broadband" booster, which means it is limited by the FCC in its gain. Depending on the band, the Fusion4Home has between 57 to 68 dB gain. These are solid numbers for a booster in this price range.

While you will get a meaningful boost from the Fusion4Home, you should only expect a large coverage area if your outdoor signal is quite strong. If your outdoor signal is quite weak, you should only expect to cover one room with better signal.

One unusual quirk about the Fusion4Home is that it uses F-Type connectors and 75 Ohm RG11 cable between the outdoor antenna and the booster, but an N-Type connector and 50-Ohm cable on the indoor end. This can be slightly frustrating, particularly if you want to shorten any of the included cables.

Cel-Fi QUATRA 4000c

Enterprise-grade booster that uses Ethernet cable for signal distribution


Uses Cat 6 cable instead of coax

Industry-leading 100 dB gain

Excellent performance even when signal outdoors is weak

Supports all three major carriers

Robust monitoring and alarming


More involved installation process

Relatively expensive, but also available in cheaper dual carrier (QUATRA 2000) and single-carrier (QUATRA 1000) models


  • If you're deploying in a larger home or office, you may want to consider an enterprise-grade device to ensure consistent coverage.

  • The Cel-Fi Quatra 4000c and its siblings (the dual-carrier QUATRA 2000 and single carrier (QUATRA 1000) models are the leading enterprise-grade boosters available today.

Before you buy:

  • Talk to us. You can't buy the QUATRA 4000c without working with one of our Signal Specialists, who will help you design a system to meet the building's needs.

The Details

The Cel-Fi QUATRA product line is the best-in-class in-building enterprise-grade booster system.

As long as there is signal outdoors, the QUATRA can amplify and redistribute that signal indoors. A single "network unit" can feed multiple "coverage units" allowing the system to scale to buildings that are tens of thousands of square feet.

The QUATRA lines combine the 100 dB gain of the lower-end Cel-Fi GO X with three main features:

  • Robust enterprise reporting and alarming
  • Cat 6 distribution instead of coax
  • The ability to scale coverage by connecting multiple coverage units to a single network unit

weBoost Installed | Office 200 (473047)

The only booster that includes installation in small and medium-sized commercial spaces


Includes nationwide installation in commercial spaces up to 35,000 square feet

Includes 2 indoor antennas


Will only cover a large area if outdoor signal is strong

Omni outdoor antenna limits performance


  • If you need coverage in a business location and outdoor signal is strong, the weBoost Installed Office 200 is a solid choice.

  • However, don't expect the best performance. The broadband booster technology, and outdoor omni antenna, and RG6 cable all work to limit coverage.

Before you buy:

  • Take signal measurements outside your building using an Android phone. The Office 200 will work best if you have at least -80 dBm signal on the carriers you want to boost.

  • Talk to our Signal Specialists. We can help you determine if the Office 200 makes sense for your application.

The Details

The weBoost Installed Office 200 is the only booster that comes with turn-key installation included.

The weBoost team have partnered with OnTech to perform turn-key installs across the US. The Office 200 package includes a special code that you can use to book your install appointment online. OnTech's technicians will come armed with the excellent Cell Linq Pro Signal Meter to help them get installation right.

However, the Office 200 has a few limitations that hold the unit back:

  • The unit only comes with an omnidirectional outdoor antenna. This means that the outdoor antenna can't be aimed at the nearest towers to optimize signal quality.
  • The Office 200 uses the same broadband, passive boosting technology as the rest of the weBoost product line. This means that the unit's gain is limited to 70 dB, and best results will only be seen when outdoor signal is strong.
  • OnTech's technicians run RG6 coax cable, which is a relatively lossy cable. Depending on the strength of the outdoor signal, you're limited in terms of the length of cable that you can run.

Talk to us before to purchasing to help make sure that the Office 200 is the right fit for your application.

Please note: the Office 200 can only be installed in commercial buildings. If you're looking for home installation, look at the weBoost Installed Home Complete instead.

CEL-FI GO G43 Multi-Carrier Smart Signal Booster

100 dB of gain across three carriers simultaneously


Universal Coverage for Buildings Up to 20,000 Sq Ft

Cloud monitoring included


Full 5G coverage coming via software update in 2024


  • CEL-FI GO G43 is engineered and FCC-approved for up to 100 dB of gain

    The 30 dB extra amplification means that the G43 can cover the same area as approximately 11 standard boosters.

  • The best DAS monitoring tool available today.

    CEL-FI’s WAVE portal makes remote monitoring straightforward and enables advanced optimization during installation.

  • Future-proofed for 5G

    CEL-FI GO G43 supports 4G LTE and 5G-DSS out of the box. It will connect to and boost these frequency bands automatically at setup. A firmware update in 2024 will automatically unlock full 5G NR support

Before you buy:

  • Talk to us

    Unsure whether the G43 is a fit? Talk to our Signal Specialists. We can help you take signal measurements and make sure that you're making the right choice.

The Details

There's one big reason why the CEL-FI GO G43 makes it to our list of best signal boosters: no other signal booster offers up to 100dB of gain across 3 networks.

Most signal boosters are limited to 70 dB gain, but thanks to CEL-FI’s proprietary 4th-generation IntelliBoost Chip, the CEL-FI GO G43 is FCC-approved for up to 100 dB of amplification.

The Intelliboost technology dynamically optimizes the boosted signal in real time to provide the best connection possible. The 30 dB extra gain means that the G43 can cover the same area as approximately 11 standard boosters.

The GO G43 also offers users unbeatable remote monitoring. CEL-FI's WAVE Portal, available on desktop, iOS and Android allows users to customise their installation during setup and configure ongoing management.

Finally, this is also one of the best options for 5G boosting and future-proofing installations. At present, the CEL-FI GO G43 supports 4G LTE and 5G-DSS (not quite full 5G).

A firmware update in 2024 will automatically unlock full 5G NR support on the same frequencies it uses today. That's proper, no compromises 5G.

One word of caution - the G43 does not and will not support the n41, n71, or n77 frequency bands used for T-Mobile 5G.

The Best AT&T Signal Boosters
For Cars and Pickup Trucks

Best Overall

weBoost Drive Reach

High uplink power make the Drive Reach our top AT&T signal booster for cars


Unmatched 26 dBm uplink power

Excellent hardware design


Relatively expensive


  • Uplink power is the spec to check for in-vehicle boosters.

    More uplink power allows you to connect further from the tower. That's specifically where the Drive Reach shines.

  • If you have the budget, there's no better AT&T booster for cars and trucks available on the market today.

Before you buy:

  • Heads up: don't buy the Drive Reach expecting "wireless" coverage.

    For best results, you'll want to keep your phone within a couple of feet of the Reach's in-vehicle antenna.

The Details

Vehicle boosters are very different to building boosters.

When you're driving around, you move from areas with very strong signal to areas with very weak signal. It's when you're at the very edge of cell coverage and signal is the weakest that a booster makes a difference.

The reason your phone stops working at the edges of cell coverage in rural areas is that the signal from your phone can no longer reach the tower. The limiting factor is the transmit (or "uplink") power.

The cell tower's signal can easily reach your phone since towers transmit at very high power levels. But your phone is battery-operated and limited in terms of its transmit power, and the signal doesn't make it back to the tower.

That's where a booster can help. And, specifically, it's where the weBoost Drive Reach shines. It has the highest uplink power of any booster on the market at 26 dBm.

The gain of broadband vehicle boosters is limited by the FCC to 50 dB. Unfortunately, that means that in-vehicle boosters are never truly "wireless" - you'll get the best results if you keep your phone within a foot of the indoor antenna. We recommend using hands-free calling for best results.

weBoost Drive Sleek

If you're budget-conscious, take a look at the Drive Sleek


Nicely designed cradle fits almost any phone

Great value


Lower performance than our top pick

Only works with one phone at a time.


  • Can't afford to spend $500 on our top pick? The weBoost Drive Sleek will boost signal for a single phone, but don't expect a similar improvement to the Drive Reach.

  • The Sleek is a "cradle" booster that requires you to place your phone in a holster.

Before you buy:

  • Make sure you understand the compromises you're making (single-device, lower uplink power/performance) compared to the more expensive Drive Reach.

The Details

At $200, the weBoost Drive Sleek is an excellent value. We're particularly big fans of the cradle format, which keeps your phone near the booster's antenna, even though it limits you to boosting signal for just one phone.

As we explained in our Drive Reach review above, uplink power is the critical spec when it comes to vehicle boosters. The weBoost Drive Sleek is limited to a maximum 22 dBm uplink transmit power, compared to 26 dBm for the Drive Reach. 4 dBm might not seem like a whole lot, but it actually has a big impact on real-world performance.

That being said, the Drive Sleek is less than half the price of the Reach. If you're on a budget, the Sleek is a solid performer that's worth consideration.

The Best AT&T Signal Booster
For RVs

Best Overall

weBoost Drive Reach RV (470354)

The best-performing AT&T booster that can be used both when stationary and when moving


Unmatched 26 dBm uplink power

Excellent hardware design


Limited coverage area - signal drops off quick from internal antenna

Omnidirectional outdoor antenna makes it less effective when your RV is camped and stationary


  • Where the Drive Reach RV shines is in uplink power, which tops out at 26 dBm. When you're out on the edge of coverage, this is the single spec that matters the most. There's no other booster that will work as well as the Reach at the edges of AT&T's network.

  • While the Drive Reach has great uplink power, it is limited by the FCC to just 50 dB gain, which means it won't provide a large coverage area. You'll need to keep your phone or hotspot near the indoor antenna for best results.

Before you buy:

  • Since the Drive Reach doesn't offer much of a coverage area, you need to figure out how to spread the data rates available next to the booster around the RV and camp site. We recommend either tethering other devices via wifi, or using a 4G/5G hotspot.

The Details

The weBoost Drive Reach RV is our top recommended RV booster. It's high uplink power rating (23 dBm) means that the Reach RV will allow you to connect where other boosters won't.

However, there are two caveats to be aware of:

  1. The Reach RV is a broadband mobile booster and limited by the FCC to 50 dB gain. This means that it won't have much of a coverage area - you'll need to keep your phone or hotspot near the indoor antenna to connect. You may want to keep one device near the booster and use wifi to connect other devices.
  2. The Reach RV comes with an omnidirectional outdoor antenna. Using a mast with a directional antenna (see our other recommendations below) may work better when your RV is stationary and parked.

We think the Reach RV is the right compromise between mobility and signal performance for most users, but if you're primarily concerned about boosting signal when your RV is parked and stationary, take a look at our next option.

For Stationary Use Only

weBoost Destination RV (470159)

Best AT&T signal booster for use in stationary RVs


Includes 25' telescoping mast and directional antenna that help you get above obstructions to the best signal available

Excellent uplink power rating (25 dBm)


Can't be used when RV is moving

A bunch of setup each time you move from one location to another


  • If you spend most of your time in your RV camped out in one location, the weBoost Destination RV is the best AT&T RV booster available.

  • Unlike the Drive Reach RV and other mobile boosters, the FCC allows stationary devices to have 65 dB gain. the extra gain allows for wireless coverage up to 30 ft away from the indoor antenna.

Before you buy:

  • Just remember: the Destination RV can't be used on the road, only when you're parked. It's really the only drawback of the unit.

The Details

Many RVs and trailers spend most of their time stationary in campgrounds. And campgrounds often don't have great cellular signal.

The weBoost Destination RV is designed specifically to provide the best signal when RVs are stationary. With a mast, directional antenna, and up to 72 dB gain, the Destination RV is designed around use in one specific location at a time.

The FCC's rules limit the gain of cellular amplifiers to 50 dB when moving, and to 72 dB when stationary. The Drive Reach operates under the second set of rules for stationary boosters. That means that each time you park your RV, you'll need to pull out the 25' extendible mast, and aim your outdoor antenna towards the nearest tower. But the included mast allows you to get above obstructions to the best AT&T signal available, and means for those willing to take the extra time, they'll see even better results than with our top-recommended Drive Reach.

If you want connectivity while camped in remote areas, the RV 65 is hard to beat.

The Best AT&T Cell Signal Boosters
For Boats

Best Overall

weBoost Drive Reach Marine Kit

The best AT&T signal booster for marine and boat applications


High uplink power means the best offshore connectivity

Includes weBoost's tried and tested marine antenna


Signal attenuates quickly as you move away from rebroadcast antenna, so for best result devices should be kept nearby


  • When you're out on a boat, signal gets weak as you move away from shore. The key to better coverage is a booster with high uplink power, and that's where the Drive Reach Marine shines. No other booster compares.

  • Because the Drive Reach is classified by the FCC as a "mobile booster" it's limited in gain. You won't get a huge coverage area, and might want to consider tethering or using a hotspot to give other devices access via WiFi.

Before you buy:

  • Make sure you understand the coverage limitations of the Drive Reach. You'll need to keep your phone or hotspot right near the Drive Reach's paddle antenna for best results.

The Details

The weBoost Drive Reach Marine Kit is the best AT&T marine booster kit on the market today. We've been told time and time again that it provides the best coverage when you're off-shore.

The reason the Drive Reach Marine kit works so well on boats is that it's been designed to have the highest uplink power possible (26 dBm!). When you're at the edges of cell coverage, uplink power is what helps you stay connected for voice and data calls.

However, even though it's our top booster, the Drive Reach Marine isn't without compromises.

Like all marine kits, the Drive Reach Marine is considered by the FCC to be a broadband, "mobile" booster kit. That means it is limited to 50 dB gain. The result of this lower gain number compared to "stationary" boosters is that it won't provide much of a coverage area - just a few feet at most.

So, for best results, you'll need to keep your AT&T cell phone or hotspot near the kit's rebroadcast antenna. You may want to consider use a hotspot to rebroadcast the 4G LTE of 5G cellular signal as WiFi if you need wireless cellular coverage.

The Best AT&T Cell Phone Signal Booster
For 4G/5G Routers and Modems

The best option for boosting signal for 4G and 5G AT&T routers and modems actually isn't a traditional "signal booster" at all.

We actually recommend connecting MIMO antennas directly to your hotspot, without any kind of booster at all.

Check out our antenna guides for 4G/5G hotspots to find information specific to your model, or look at the antennas we recommend below.

Some of the most popular AT&T hotspots include the Netgear Nighthawk M1 MR1100 and the Netgear Nighthawk 5G.

MIMO Log Periodic Antenna Kit For Hotspots

Great performing antennas, work best if you know direction of towers or have line of sight


Includes everything needed to connect to most hotspots/routers

Up to 11 dBi gain

Optional lightning surge protectors


Works best if you know the direction of your nearest towers or have line-of-sight


  • Our MIMO log periodic antennas are our top external choice recommendation for most people.

  • These antennas have relatively high gain, and work best if you know the direction of your nearest towers, and ideally if you have line of sight.

Before you buy:

  • Check the connectors on your hotspot or router prior to purchasing.

  • Most hotspots have either TS9 or SMA external antenna ports, but some hotspots don't have external antenna ports at all, and can't be used with these antennas.

  • You can also look for your hotspot in our device-specific external antenna guides.

The Details

If you're looking to get the very best data rates possible, using MIMO antennas with a 4G or 5G hotspot or router is your best bet. MIMO antennas work even better than boosters.

Log periodic antennas are highly directional antennas with between 8 and 11 dBi gain. These log periodic antenna kits combine two antennas in a MIMO configuration and include ultra-low-loss coax cable, adapters, and a J-Mount.

Not only are MIMO antennas cheaper than boosters, but they also get you the very best data rates. We couldn't recommend them more highly.

If You Don't Have Line of Sight

MIMO Panel Antenna Kit For Hotspots

Slightly lower gain than our top pick. Use these for an easier, simpler install if you don't know the exact direction of the nearest towers


Easier to aim than other MIMO antennas due to lower directivity

Easy to assemble


Slightly lower gain than our log periodic antenna kits, and thus slightly lower performance


  • If you don't know the exact direction of the nearest cell tower, and you don't have clear line of sight, this MIMO panel antenna kit is the best choice.

  • The MIMO panel has lower gain than our log periodic antennas. As a result, they're less directionally sensitive. That makes them easier to set up and aim.

Before you buy:

The Details

This MIMO Panel Antenna Kit includes everything you need to improve signal for our 4G or 5G AT&T hotspot or router.

These antennas have slightly lower gain (8 dBi) than our log periodic antennas (11 dBi). That makes them meaningfully more forgiving: they're easier to set up and less sensitive to the exact direction of the nearest tower.
