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.

This booster can cover an area of up to 500 square meters, making it suitable for medium homes, offices, and even warehouses.
- How does the signal booster work? - The signal booster works by capturing weak cellular signals from outside and amplifying them for better reception inside your space. It has an outdoor antenna that collects the signals and sends them to the booster unit, which then extends the boosted signal through an internal antenna to your devices. However, it cannot create a signal on its own; it only amplifies existing signals.
- Can I install the booster myself? - Yes, the installation process for the 3G signal booster is designed to be simple and user-friendly. The kit includes all necessary components for installation, such as the outdoor antenna, booster unit, and indoor antenna. Just follow the installation guide, and after a loose setup to test the best placement, you secure everything in position. Many find it easy to complete on their own.
- What happens if there is no signal outside? - Unfortunately, if there is no cellular signal outside your location, the booster will not work. The signal booster requires a weak signal to amplify. So, it's essential to check your outdoor signal before installing the device. You can use your phone or specific apps to check the external signal quality.
- Is it safe to use a signal booster? - Yes, using a signal booster is safe as it complies with regulatory standards.
