#### 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.

1.  What is a 4G LTE Mobile Signal Booster? - A 4G LTE mobile signal booster is a device that helps improve your mobile phone signal at home or in other indoor spaces. It takes weak signals from outside and makes them stronger, so you can have better calls and faster internet on your phone.
2.  Which mobile networks can I use with this booster? - This signal booster works with several mobile networks in the Netherlands, including KPN, Vodafone, Tele2, Telfort, Ziggo, Lebara, Lycamobile, Robin, Simyo, and Youfone. It helps improve 4G mobile services for all of these providers.
3.  How do I check if my phone supports 4G Calling? - To check if your phone supports 4G Calling (also known as Voice over LTE or VoLTE), you can dial \*3001#12345#\* on your iPhone and look for 'Frequency Band Indicator' in the 'Serving Cell Info.' You can also use apps like CellMapper or Network Signal Info Pro.
4.  How big of an area can the booster cover? - The mobile signal booster can cover an area of up to 250 square meters, making it ideal for medium-sized spaces such as homes, cafes, and restaurants. This means you can enjoy better signal strength in various indoor locations.
5.  What if there is no signal outside? - It's important to know that the signal booster can only amplify existing signals. If there is no signal available outside, the booster will not be able to create one and won't improve your phone's reception.

8.  What is the purpose of the higher gain Yagi antenna? - The higher gain Yagi antenna is an upgrade that can improve the performance of the booster, especially if you get weak signals indoors. It's useful if your phone displays only one or two signal bars, or if you need to boost your signal from outdoors.
9.  How can I protect my signal booster from lightning strikes? - You can choose to add a Lightning Surge Protector to your setup. This device helps protect the booster from high electric surges caused by lightning strikes. It's simple to install and can keep your equipment safe.
10.  How many users can connect to the booster at once? - The signal booster can support up to 25 users simultaneously. This means that several people can enjoy improved signal strength and faster internet connections at the same time.
