Cellphone Signal Booster
The system consists of an external antenna (Aluminum Yagi antenna pictured below) which is directed towards the cell phone tower which you would like to use. On the inside of your house there is a two-way booster connected to a small black antenna which you can place in a central area.
The system gives you a full signal in a radius of 10m ( C10 ) or 30m ( C23 ) around the internal antenna. There is no need to attach your cell phone to the system.
The C10 gives a full signal in a radius of 10m from the internal antenna:
The C23 gives a full signal in a radius of 30m from the internal antenna:
