How to optimise your setup


How To Install A Signal Booster

Like all of our other repeaters / boosters / amplifiers; this system is refined around a simple and fast installation process (Plug and play).

One Standard External Panel Antenna: This accessory comes free of charge with the booster, which is meant to be mounted in a good signal location outside the building and helps to pull the signal from the tower of the service provider via the coaxial cable to the base unit. (Mobile booster)

10 METRES COAXIAL CABLE: Included as a free component with the booster kit, it facilitates the connection of the outdoor antenna to the indoor booster unit but the cable can also be used for indoor purposes if necessary.

MOBILE BOOSTER: The cell phone enhancer is an indispensable piece of the system, as soon as the signal is transmitted from the roof antenna via the coaxial cable, it expedites to broadcast the mobile reception in the property through the internal aerial that should be physically paired to the Booster (Base Unit).

INDOOR ANTENNA: This is a small standard whip aerial that’s also included in the package. The Mobile booster uses this indoor aerial to distribute amplified and purified mobile phone reception internally.

AC/DC POWER SUPPLY: The AC/DC power supply and power plug provide the Booster with all the electrical power that it requires to perform.

There are a few reasons that explains why people struggle with such poor coverage of mobile phone signals within certain areas and places. All of those factors vary from materials used in the design of the building to internal components such as insulation materials. Mountainous views and densely tall trees that cover some areas also lead to how minimal cell phone signals can penetrate. But with our signal boosters, you’re sure to resolve this problem once and for all and for you to enjoy great mobile phone and internet data coverage.
