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 helps improve your mobile network signal. It captures weak signals from outside, boosts them, and then transmits the stronger signal indoors, making calls clearer and data faster.
- Which mobile networks does the booster work with? - This booster works with several networks in the Czech Republic like Vodafone, T-Mobile, Mobil CZ, Kaktus, O2, and PrimeTel. It boosts both voice calls and 4G internet not just for one but multiple networks at the same time!
- How big of an area can this booster cover? - The booster can cover an area up to 200 square meters! This makes it great for small homes, offices, or apartments, ensuring everyone inside has a better signal for calls and internet.
- Can I use the booster if I have no signal outside? - Unfortunately, if there's no signal coming from outside, the booster cannot create a signal. It only amplifies the signal that it receives. So, there needs to be some outdoor signal for it to work.
- How do I check my phone's frequency band? - To check your phone's frequency band, you can dial *3001#12345#* and press the call button. Then click on 'Serving Cell Info' and check the 'Freq Band Indicator' to see if it shows Band 20 or Band 3.
- Is the installation of the booster easy? - Yes! The booster kit comes with everything you need, including an outdoor antenna, indoor antenna, cables, and a power adapter. It’s designed for easy installation, even if you’re not very tech-savvy.
- Why should I upgrade to a higher gain antenna? - Upgrading to a higher gain antenna can significantly improve the booster’s performance, especially if your mobile signal indoors is weak or if you have only 1 or 2 bars of signal outside.
- What does the Lightning Surge Protector do? - The Lightning Surge Protector helps protect your signal booster and other equipment from electric surges caused by lightning strikes. It's easy to install and adds an extra layer of safety.
- Can I use this booster for both calls and internet? - Absolutely! This booster improves both voice calls and 4G LTE internet speeds. So you can enjoy clear conversations as well as fast downloads and uploads at the same time.
- How many users can connect to the booster at once? - The booster can support up to 20 users at the same time! This makes it perfect for families or small teams in an office where multiple devices need a strong signal.
