You will likely need to place an antenna on top of your home if you really get zero reception. Try this thread-
I have Verizon wireless cell phone service that works well in our area, but a lot of rebar was used in the construction of our house, and I am guessing all that metal is the reason I get ZERO reception inside. Are there any signal boosters that work? I know that there are some for the car that people have said helped.
