### Custom your solution
#### **Expandable coverage by adding indoor antenna if the outside signal is strong.**
### **How It Works**
#### 1
**Receives signal**
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
#### 2
**Boosts signal**
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
#### 3
**Broadcasts signal**
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**
1. Connect the indoor antenna to the MS port.
2. Connect the outdoor antenna to the BS Port.
3. Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
4. Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
5. Power on the booster and check the signal strength.
6. 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.
