6.How to install a mobile signal booster?

Though the configuration of some models can differ, the general principles of installation are always the same. One antenna should be placed outdoors. The best location is on the roof. The second antenna and the booster box should be installed indoors. It is important to ensure the necessary vertical distance between two antennas. All the elements should be connected with coaxial cables. You will find all the precise instructions in the User’s manual that you will get together with your booster. It’s important to note that we sell only full kits, which means that you do not need to buy anything additional.
