How To Install A Signal Booster

Setting Up Your SBG1800 Pro Booster

Step By Step Install Of A Signal Booster


This particular Cell phone repeater is no different in the installation process from all of our other boosters and all the accessories are somewhat similar 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 function is to pull signal from outside through coaxial cable so that it can retransmit stronger and purer signal through the repeater which in turn amplifies the signal and redistributes a much better coverage in the property for up to 500sqm.

10 METRE 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 help in transferring signals from the external antenna into the repeater.

INDOOR GSM REPEATER: The mobile phone booster is the essential part of the puzzle, once signal is transferred from the roof antenna through the coax cable, it helps amplifies the mobile phone signal in the building through the indoor antenna.

INDOORS ANTENNA: This is a distribution antenna, the mobile booster uses this high power indoor antenna to distribute signal internally.

AC/DC POWER SUPPLY: The AC/DC power supply and power plug supplies the repeater with all the currents it need to function.

Likely Reason why you are experiencing poor mobile phone signal in your property

There are few reasons why we face low reception of mobile phone signal in buildings and around some areas. Some of these factors range from the distance between the building and the Cell Phone Base Station, which has a major effect on the signal level in the area, especially in rural areas, where very little or no mast is located.

The second reason is likely due to materials used during the construction of the building, this would normally range from the materials used for insulation, the treated glass doors, windows and the concrete walls demarcating the wall in the properties. These materials often work against the RF signals by preventing its penetration through them into the building.

Area and regions sounded by tall buildings, trees, mountainous terrains. deeps etc suffers huge Mobile phone signal coverage.

However, Our boosters is capable of breaking all barriers and enhancing mobile phone signal coverage in this areas leaving you in the end with fully enhance signal.
