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.
Get stronger signal

Normal Cell Coverage
Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.
Signal Coverage with our booster
Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.Installation
- Connect the indoor antenna to the MS port.
- Connect the outdoor antenna to the BS Port.
- Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
- Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
- Power on the booster and check the signal strength.
- Adjust the outdoor antenna until you get the best signal strength.
IMPORTANT NOTE:
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

- What is a 4G LTE signal booster? - A 4G LTE signal booster is a device that improves mobile phone signals inside your house or office. It works by receiving the weak signal from outside and amplifying it, making it stronger so you can connect better. This can help you make clearer calls, send texts quickly, and enjoy faster internet.
- Who can benefit from using a 4G LTE signal booster? - Anyone can benefit from a 4G LTE signal booster, especially people living in areas with weak mobile signals. Families with multiple devices from different mobile networks will find it especially helpful, as this booster works with many service providers like Vodafone, T-Mobile, O2, and more!
- How does the booster work? - The booster works by capturing a weak signal from outside using an outdoor antenna, then amplifying that signal, and finally redistributing it inside your home or office through indoor antennas. This way, you get better coverage throughout the area, which can span up to 500 square meters!
- Do I need to have service outside for the booster to work? - Yes, the booster can only make a weak signal stronger; if there is no signal outside at all, the booster will not work. It’s like trying to turn on a light in a dark room with no electricity.
- What is the difference between 4G calling and regular calls? - 4G calling, also known as Voice over LTE or VoLTE, allows you to make clearer voice calls using the 4G network instead of the older 2G network. This means your calls will sound better and connect faster when you use a booster that supports 4G calling features.
- How can I check if my phone supports 4G calling? - You can check if your phone supports 4G calling by dialing *3001#12345#* and then pressing the call button. Look for the 'Freq Band Indicator' under 'Serving Cell Info' to see the supported frequency bands. You can also use apps like 'CellMapper' or 'Network Signal Info Pro'.
- Is installation of the booster complicated? - Not at all! The signal booster kit comes with everything you need, including an outdoor antenna, indoor antenna, cables, and a power adapter. Most people can install it themselves easily without needing special tools.
- Can I use the booster with any mobile carrier? - Yes! This booster is designed to work with all major mobile carriers in the Czech Republic, such as Vodafone, T-Mobile, O2, Mobil CZ, and more. So no matter which service provider you use, you'll get better coverage!
- What if I need longer cables for installation? - If the standard 10 meters of external cable isn’t enough for your setup, you have the option to upgrade to longer cables. This way, you can position the antennas where they can get the best signal.
- What are the advantages of using a higher gain antenna? - Using a higher gain Yagi antenna can significantly improve the performance of your signal booster. It helps capture and enhance the signal better, especially if your phone shows only 1 or 2 signal bars. This can result in stronger, clearer calls and faster internet.
