It’s a device that boosts your current weak 2G 3G 4G AND 5G signals and then delivers the stronger signal to your cell phone.

1. Outside Antenna: Pulls in the existing signal from the cell tower and sends it to the amplifier.
2. Amplifier: Boosts that signal multiple times and sends it to the inside antenna.
3. Inside Antenna: Broadcasts the boosted signal to the area in need.

Cell phone signal boosters generally come in two categories: for buildings such as homes and offices and for vehicles such as cars, Trucks and boats.

Absolutely.

There are signal boosters for all different needs for homes and for All Vehicle types, Caravans and Yachts, and they improve 2G 3G & 4G LTE and 5G signals inside the buildings and inside Yachts, all vehicle types. Although you may get some coverage outside the building, they are not designed for this purpose. They are generally fixed installations and powerful performers. 

Signal boosters for cars, trucks, RVs, and boats boost 3G & 4G LTE and 5G signals inside your vehicle. Some units can be used indoors with additional accessory kits.

Whether you’re looking for something affordable, commercial-grade, or custom, we provide a variety of solutions. Start with our Buyer’s Guide to get our best recommendations.

No, you don’t need an internet connection, but you do need an existing cell phone signal. If there is no existing signal, then you’re in a no service dead zone, meaning the amplifier cannot boost what isn’t there.

3G handles talk, text, email, and basic internet use. 4G does all of 3G functions plus fast internet. Data-heavy apps and programs such as YouTube, Netflix, Pandora, Spotify, Facebook, Google Maps, Google Chrome, etc. require lots of bandwidth, so 4G and 5G speeds would be more suitable.

Yagi and omni antennas are outside building antennas. Omni antennas are omni-directional. They pull signal from every direction. Good when you’re in a location with multiple same-carrier towers or you have multiple people with different carriers. Yagi antennas are directional. They pull signal in only one direction. Good for rural remote areas when you know the location of the tower and only to boost signal for just one carrier.

Cell phone signal strength is measured in dB (decibels). Typically, -50 dB represents a great signal (full bars) and -110 dB is virtually no signal (dead zone). Cell phone signal boosters improve your coverage by amplifying signals and improving the dB gain of your cell phone. All our cell phone signal boosters have a listed dB value for better comparison.
