How It Works

1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
- Outside Antenna: Pulls in tower Signal.
- Signal Booster: Amplifies the Signal.
- Inside Antenna: Re-broadcasts Signal.
- Mobile Phone: Gets Boosted Signal.

Installation
- Mount external aerial on top back.
- Install the booster and interior antenna.
- External aerial connect to "BS" on the booster, and interior antenna connect to "MS".
IMPORTANT NOTE:
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

Application Scenarios




- What is a 3G cell phone signal booster? - A 3G cell phone signal booster is a device that enhances or amplifies weak cell phone signals, making it easier for you to make calls and use the internet on your phone. It works by increasing the strength of the signal received from the cell tower, so you can enjoy clearer calls and faster data speeds.
- How does this booster work? - This booster works by capturing the weak 3G signal outside your vehicle and amplifying it. It uses an external antenna to grab the signal and then sends it to the booster inside your car, which redistributes it through an internal antenna. This way, your phone can connect to a stronger signal.
- Which frequency does this booster support? - This booster supports the 2100 MHz frequency, which is used in Brazil by mobile networks like Oi and Algar for 3G services. It is designed specifically for enhancing 3G signals in vehicles.
- Can this booster work if there is no signal outside? - No, the booster cannot create a signal. If there is no signal outside, it won't work. The booster only amplifies existing signals, so you'll need to be in an area with some signal for it to help.
- How many devices can connect at once? - This booster can support up to 10 devices simultaneously. This means you and your friends or family members can use their phones without problems while in the vehicle.
- Is it easy to install? - Yes! The installation is quite simple and does not require complicated tools. The kit includes an easy-to-follow installation manual, so even if you are not very tech-savvy, you should be able to set it up without any issues.
- Does it use a lot of electricity? - No, the booster is designed to be efficient and uses a 12V DC power adapter, making it environmentally friendly. You can also unplug it when not in use to save power.
- Will it help reduce phone radiation? - Yes! By providing a better signal, the booster can help reduce the amount of radiation emitted from your phone. When your phone has a strong connection, it doesn't need to work as hard, which means less radiation.
- What comes in the booster kit? - The booster kit includes everything you need for installation: one car signal booster, one external antenna with a magnetic mount, a 12V DC power adapter, and an easy-to-follow installation manual. You'll have all the components needed to set it up correctly.
- Is this booster suitable for use in my country? - Yes, this booster is specially designed for use in Brazil and works well with the mobile networks Oi and Algar that provide 3G service. Just make sure you check if your mobile network is supported.
