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 and 4G LTE Signal Booster? - A 3G and 4G LTE signal booster is a device that helps improve mobile phone signals in your car or caravan. It works by boosting the existing signals from mobile networks like Telia, Elisa, DNA, and Tele Finland, making it easier for you to make calls and use data services.
- How does the signal booster work? - The signal booster captures weak signals from outside using an external aerial. It then amplifies these signals and sends them inside your vehicle, allowing your phone to connect better, resulting in clearer calls and faster internet.
- Is this booster suitable for all mobile phone operators? - Yes! This booster works with all mobile network operators in Finland that support 3G and 4G LTE services, including Telia, Elisa, DNA, and Tele Finland. It is a great solution if people in your household use different networks.
- Can I use my phone for 4G Calling with this booster? - Yes! If you have a 4G-capable phone and you are in an area where 4G Calling is available, the booster will help you make clearer voice calls. This is also known as Voice over LTE or VoLTE.
- How many devices can connect to the booster at the same time? - The signal booster can support up to 15 devices at the same time. This means you and your family or friends can all use your phones without losing signal quality!
- What frequencies does this booster work with? - The booster works on two frequencies: 800MHz and 2100MHz. These are the frequencies that many mobile networks in Finland use to provide mobile services.

- What if there is no signal outside? Will the booster still work? - Unfortunately, the booster can only enhance existing signals. If there’s no signal outside, the booster won’t be able to create one, so it won't help in areas with no coverage.
- Does using the booster reduce my phone's radiation? - Yes! When your signal is stronger, your phone doesn’t have to work as hard to connect, which can help lower the radiation levels it produces. This is better for your health.
- What comes in the signal booster kit? - The kit includes everything you need: a car signal booster, an external aerial with magnets, a power adapter for your car, and a user-friendly manual to help you install it easily.
