Ok, you are not a guy with technical background or you do not have any knowledge in installing things, that is fine. Still, if you want then you can install cell phone signal boosters by your own just by following the manual in right manner. To be very frank, installing a cell phone signal booster can be done easily by any child if the installation guide is followed right.
You will get almost everything in your booster kit which will be needed for installation like cables, screws or mounting things but the tools like screw-driver, drill machine or hammer are the things you will have to arrange. In case of cables, if it has fallen short then you can buy extra cable from online cell phone booster store. You will have to buy a cable joining unit to join the cables perfectly, lose joint will make you lose signals.
Manufacturer like weBoost (formerly known as Wilson Electronics) always provides installation guide with each booster and their guide use to be written in easiest readable pattern.
