Hi, i live in the great british counryside where mobile phone signal it terrible. I have a car antenna up in my room but it is tiny and doesnt really provide much gain. It is a flat black strip abut 10cm long that is connected to a nokia reciver which sits behind then phone. I tryed to look inside but i wuld risk breaking it whichi isnt an option as it needs to go in my car. I guess that there is something simlar to to antenna in this box that increase the gain for the mobile intergal one. I have search the net but i cant seem to find any projects for a homemade mobile phone atenna. It doesnt need to connect to the phone, it just need to work on a simliar principle to the current device just with more gain. For the cable i have some high quality co axial cable used with satellites.
Does anyone have an idea??
Thanks
