Did you find what you were looking for?
As the work of a device does not presuppose your participation, the main task for you is to install it correctly.
First of all, you need to find a good place for an outdoor antenna. The best place for it will be on the roof. But if it is not possible, you can install it outside near the window. Secondly, you need to fix another antenna and a booster box. They should be placed inside the building. The elements should be connected with a coaxial cable. Done! The problems with Kcell mobile coverage are solved!
