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 improve your mobile phone signal indoors. It takes the existing weak signal outside and amplifies it, making it stronger so you can make calls or use the internet without interruptions.
- How does the 3G Mobile Signal Booster work? - The 3G Mobile Signal Booster works by receiving the weak 3G signal from outside, boosting it, and then transmitting that stronger signal inside your home or office. This helps reduce dropped calls and improves your internet speed.
- Which mobile networks can this booster support? - This booster supports several mobile networks in Slovakia, including O2, Telekom, Orange, FunFon, Juro, and Tesco Mobile, making it versatile for many users. However, it does not work with the Swan 4ka network.
- How much area does this signal booster cover? - The 3G Mobile Signal Booster can cover an area of up to 500 square meters. This makes it suitable for medium-sized houses, offices, and warehouses, ensuring better coverage in those spaces.
- Can I use the signal booster if there is no signal outside? - No, the signal booster can only amplify signals that are already present. If there is no signal outside, the booster will not work, as it needs a weak signal to improve.
- What do I need to install the signal booster? - The kit includes everything you need for installation, such as the external antenna, cables, the booster unit, an internal antenna, and a power adapter. It’s designed to be easy to install.
- What if I need longer external cables? - If the standard 10-meter external cable is not long enough for your needs, you can upgrade to longer cables to ensure the booster can effectively capture the best signal.
- Do I need to upgrade the aerial for better performance? - If your phone shows only 1 or 2 signal bars indoors, upgrading to a higher gain Yagi antenna is recommended. This can significantly improve the signal strength inside your home or office.
- How do I protect my equipment from lightning? - You can add a lightning surge protector to your setup. This device safeguards your equipment from damage caused by lightning strikes and is simple to install.
- Is this booster compatible with 4G signals? - While this particular booster focuses on 3G signals, there are options for boosters that can also support 4G signals. For those looking specifically for 4G solutions, different models are available.
