BEST CELL PHONE SIGNAL BOOSTERS IN 2021

WEBOOST HOME MULTIROOM - 470144

Buy This Cell Phone Signal Booster If:

You have a midsize home or office with strong outside signal strength.
You have a small home or office with weak outside signal strength.
You need a versatile, scalable cell phone booster.

The weBoost Home MultiRoom is the bestselling do-it-yourself signal booster kit. It is the signal amplifier that works for most people. It can cover up to 5,000 square feet if your outside signal is perfect. Most people will probably see a coverage area of 2,000 to 3,000 sq ft. If you live in a rural area with very weak outdoor signal, expect much less coverage. This is the weakest cell signal booster you should buy if you have bad signal outdoors.

It has a nice, clean look. Its indoor panel antenna has a fabric front and looks like a part of the house. With its powerful yagi directional antenna, it can reach far away cell towers.

The weBoost Home MultiRoom boosts signal for all major North American carriers. Should you ever change carrier, the weBoost Home MultiRoom will still work. It also supports all Sprint bands for the first time on a weBoost unit.

SURECALL FUSION4HOME

You live in a small home or only need spot coverage, regardless of outside signal.
You need a simple installation.
You want a booster made for customization.

The SureCall Fusion4Home is the do-it-yourself signal booster kit we recommend most for small homes. The reason? Its antenna setup. This kit is designed to be customized. The repeater itself is powerful enough to cover a midsize home with the most effective antenna setup. It boosts all major North American carriers, so it will work on every band.

Our most affordable configuration is the omni/whip kit. It works well if you have powerful outside signal, and has a very easy installation. We do not recommend this if you have weak outside signal.

If you have weak signal outside, get the yagi/panel configuration. This can cover a midsize home with strong outside signal, as well.

In general, get a yagi outside antenna if you have weak outside signal, and an omnidirectional antenna if you have strong outdoor signal and want an easier install. The whip antennas are weaker than panel, but similarly have easier install, so which of these you get is up to you. We also offer a dome antenna configuration. Call us at 1-800-470-6777 if you’re unsure which configuration is best for you.

CEL-FI GO X

You want the most powerful signal booster on the market, no matter where you live.
You want a repeater that can be fitted for home, vehicle, and office.
You need a switchable booster that can change carriers when you need it.

The Cel-Fi GO X is the most powerful consumer signal booster we offer. It is a single-carrier booster, meaning it only boosts one of the major carriers at a time. However, this means it is significantly more powerful than any multi-carrier cell booster. If you have a family plan on a single carrier, you will be amazed at the difference a Cel-Fi GO X cell phone booster will make, no matter how weak your outside signal.

We offer it in several different configurations, and the Cel-Fi GO X is easily powerful enough to handle up to four indoor antennas.

HIBOOST 4K SMART LINK RENEWED

You have a midsize home or office with strong outside signal.
You have a small home or office with weak outside signal, or you only want spot coverage.
You want great coverage on a budget.

The HiBoost 4K Smart Link is a factory renewed signal booster by HiBoost USA. It is the same as the regular 4K Smart Link except in price. It can cover up to 4,000 square feet if you have perfect outside signal. Most people will see about 2,000 to 2,500 square feet. If you live in a rural area with very weak outdoor signal, expect much less coverage. This is the cheapest cell signal booster you should buy if you have bad signal outdoors.

It comes with a panel antenna and a yagi directional antenna. It reaches far away cell towers well. It can be linked and monitored via HiBoost’s Signal Supervisor app.

CEL-FI QUATRA 4000

You have a very large office building or commercial space.
You need a booster with the maximum amount of power.
You want a booster with a lot of bells and whistles.

The Cel-Fi QUATRA 4000 is an extremely strong industrial signal booster. It is made for commercial or industrial buildings but can be used in very large homes. It has many features, including remote signal monitoring and tweaking. It boosts all major carriers at a higher rate of power than any of its competitors, making it a no-brainer option if you’re looking to cover a very large space. It is our top recommendation for commercial buildings in rural or low-signal areas.

The Cel-Fi QUATRA 4000 is scalable based on how much area you’re trying to cover. It uses Network Units and up to 6 Coverage Units to cover all the way up to 200,000 square feet.

The FCC defines a signal booster as “devices that can help cell phone users improve their coverage in areas where they do not get a good signal.” In other words, if you live in a rural area, or really anywhere with spotty 3G or 4G coverage, signal boosters can help fill that gap. These boosters can also extend network coverage into dead zones like tunnels or subways.

Can a signal booster interfere with other wireless networks?
Older signal boosters had a tendency to disrupt conflicting wireless signals, including the signals that handled emergency and 911 calls. However, a 2014 ruling by the FCC improved cell phone signal booster designs so they won’t interfere with other wireless networks. While modern signal boosters have largely eliminated this problem, there is still a slim chance that it could interfere with existing signals.

Do you need to register your signal booster with the FCC or your wireless provider?
In short, yes. All modern signal boosters come packaged with labels provided by the FCC stating very clearly that you must register this device with your wireless provider. These labels will have a series of guidelines that must be adhered to in order to be within the legal statutes for the FCC.

What to Look For in a Cell Phone Signal Booster
Wireless Vs. Cradle
Not all cell phone signal boosters are wireless. Some boosters actually use a cradle. With a wireless model, you’ll likely pay more than if you purchased a cell phone signal booster. Conversely, wireless models are capable of providing a stronger signal to multiple devices at once. Cradle signal boosters will only amplify the signal to one connected phone but will be easier on your pockets.

Band Coverage
Cell phone carriers, small and large, use a number of bands with different frequencies in providing cellular service to customers. With distinct bands and various frequencies, you need a booster that can sustain your particular cellular provider. The best cell phone signal boosters cover five bands in addition to 4G. Depending on your carrier and phone, it’s acceptable to select a signal booster with less coverage as long as the bands align to provide the requisite coverage.

Signal Strength
There are cell phone signal boosters on the market with both high-gain and low-gain antennas. Look for a booster with a high-gain antenna. With a high-gain antenna, you’ll want at least 5dBi if you live in a rural area without nearby cell towers. That said, if you live in a more urban area, your signal will likely be obstructed by terrain or builders. City dwellers will be satisfied with a lower-gain antenna.
