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 mobile signal booster? - A mobile signal booster is a device that helps enhance the mobile phone signal in your home or business. It captures weak signals from outside, amplifies them, and then broadcasts the stronger signal inside, allowing you to make calls, send texts, and use the internet more reliably.
- How does the 3G - 300m2 booster work? - The 3G - 300m2 booster works by using an external antenna to pick up the weak mobile signal from the outside. It then boosts this signal and sends it through an internal antenna, giving you better coverage in areas like your home, cafe, or restaurant.
- Can the booster work with all mobile networks? - This mobile signal booster specifically works with O2, Telekom, Orange, FunFon, Juro, and Tesco Mobile 3G networks in Slovakia but does not support Swan 4ka. Always check your mobile carrier to ensure compatibility.
- How far can the booster cover? - The 3G - 300m2 booster can improve your mobile signal coverage up to 300 square meters, making it perfect for medium-sized spaces like homes, cafes, and other venues.
- Do I need a good signal outside for the booster to work? - Yes, the mobile signal booster can only amplify an existing signal. If there's no mobile signal outside, the booster won’t be able to help you inside.
- What is included in the booster kit? - The kit contains everything you need for setup, including an external antenna, cables, the booster unit, an internal antenna, and a power adapter. It’s designed for easy installation.
- What if I need a longer external cable? - If the included 10-meter external cable isn't long enough for your setup, you have the option to upgrade to a longer cable to suit your needs.
- How can I upgrade my external aerial? - To boost performance, especially if you have a weak signal indoors, you can upgrade to a higher-gain Yagi antenna, which can help capture more signal from outside.
- What is a lightning surge protector? - A lightning surge protector is an accessory designed to protect your booster from power surges caused by lightning strikes. It ensures that your equipment remains safe and functions properly.
- How many users can this booster support? - The 3G - 300m2 booster can support up to 30 users simultaneously, making it ideal for medium-sized locations or multiple users in a home.
