How to install a cellphone signal amplifier:

No technical expertise is required to install your GSM repeater, so you can easily install it yourself.


The installation, very simple, is done in four steps:

1st step: Place the outdoor antenna on the roof or a wall of the building in the direction of the operator's relay, if possible without visible obstacles.

Step 2: Connect the repeater to the outdoor antenna using the cable provided.

Step 3: Connect the indoor antenna to the repeater.

4th step: Connect the power supply.




A GSM amplifier is a device combining a receiving antenna, one or more transmitting antennas and an amplifier box. The latter compensates the signal transmission losses by amplifying the received mobile signal, we also speak of "gain db".

The mobile phone signal booster increases network coverage in places where signals are not received properly and thus improves the reception of your mobile phone

NOTE: A GSM repeater does not amplify a non-existent signal. For an efficient installation, you must therefore initially benefit from a minimal reception near the building (minimum of three signal bars on your phone).

How does a booster work?

improve reception mobile phone

A GSM signal amplifier is composed of a repeater, an external antenna and one or more internal antennas.

1- The mobile network signal is received by the outdoor antenna

2- It is transmitted to the repeater

3- The repeater reinforces this received signal to transmit it to the antenna located inside the building.

Once enhanced, the signal strengthens network coverage near the indoor antenna. It is therefore necessary to place the indoor antenna in the room where you want to optimize the reception of the mobile signal.
