Anyone have experience installing Bi-directional Amplifier units for cell phones? I have a customer that wants nextel users to be able to use cell phones inside his grocery store. We have service outside & simply need to bring in. I am familiar with several brands but don't have experience to compare them.

I have put a few of these in with great success.
