How To Install A Signal Booster

We’ve gathered all the constructive insight from our customers and from our thorough analysis, we’ve then built our devices around the easy and quick installation (Plug and play system).

This solution is no different in the setup process from all of our other boosters and all the components are reasonably alike except for the bigger units. As stated earlier it comes with:

AN OUTDOOR ANTENNA:  This accessory is one of the most needed kit in the installation of the booster, it is mounted outside and its main purpose is to pull signal from outside through coaxial cable.

10 METRES COAXIAL CABLE: The coaxial cable is connected to the outdoor antenna on the roof on one end and the second end is connected to the mobile booster that will be located inside the building. The cable helps in transferring signal from the external antenna into the repeater.

INDOOR REPEATER/BOOSTER: The cellphone booster is the quintessential piece of the puzzle, once the signal is established from the external roof antenna, it then facilitates signal magnification on the 3G cellphone & on related devices in the building through the indoor antenna.

INDOOR ANTENNA: This is the donor antenna, the cellphone signal booster uses it to spread enhanced 3G coverage indoors.

AC/DC POWER SUPPLY: The AC/DC power supply and the power plug provides the amplifier with all the electricity it requires to perform.

Likely Reason For Your Poor Signal Coverage

There are few factors that can cause poor signal penetration into buildings or poor signal coverage in an area. From the distance of of the cell towerfrom the property or area, to the materials used in the design of a building to the internal components, such as insulation materials, the thickness of walls, metal roofs and so on. Mountainous regions, hills, valleys and heavily tall trees that cover some areas may also result in a minimum 3G cell phone signal. But with our signal boosters, you’re sure to resolve this problem once and for all and you can now start to enjoy great mobile phone connectivity.  Just give it a try, you have nothing to lose but so much more to gain.
