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 Mobile Signal Booster? - A 4G LTE mobile signal booster is a device that helps improve the 4G mobile signal in your area. It works by taking the weak signal from outside and making it stronger, so you can enjoy better internet and clearer voice calls inside your home or business.
- How does the signal booster work? - The signal booster captures the existing 4G LTE signal from outside using an external antenna, then amplifies this signal, and sends it inside through an indoor antenna. This means if you had a weak signal, now you'll have a much stronger one to use!
- What areas can the booster cover? - This booster is designed to work in areas up to 250 square meters. It's perfect for places like homes, cafes, restaurants, clubs, and more. If you have a medium-sized space, this booster will help improve your signal.
- Which mobile networks does this booster support? - The booster works with several mobile networks in Finland, including Telia, Elisa, DNA, and Tele Finland. As long as you are using a 4G compatible device, this booster will help improve your signal for these networks.
- Can I use this booster if there is no signal outside? - No, the signal booster cannot create a signal; it can only amplify an existing one. If you do not have any signal outside, the booster will not be able to help you.
- Do I need special tools to install the booster? - No special tools are needed! The kit comes with everything you need for installation: antennas, cables, and the booster itself. It's designed to be easy to set up for anyone, even if you're not very tech-savvy!
- How do I check my phone's frequency band? - You can find out if your phone supports the right frequency band by dialing *3001#12345#* on your iPhone, then pressing call. Look for 'Serving Cell Info' and check the 'Freq Band Indicator' to see what band your phone is using.
- What is the upgrade external aerial option? - The upgrade external aerial is a higher gain antenna that can help improve your booster’s performance if you have a weak signal indoors. If your phone shows only 1 or 2 bars of signal strength outside, upgrading to this aerial can make a huge difference!
- Why would I need a lightning surge protector? - A lightning surge protector helps keep your equipment safe from power surges caused by lightning. If your antenna is hit, the protector ensures your booster and other devices won't be damaged. It's an easy addition that can save you from future problems.
- How many users can connect to the booster at once? - The booster can support up to 25 users at the same time. This means that multiple people can enjoy a strong 4G signal in the same area without any issues.
