New in Package Amplified Glass Mount Cellular Phone Antenna

This is a new in the package antenna. It is a glass mounted cellular antenna. I don't know much about them as my husband bought it and we don't need it. He has quite the collection of cords, wires, and other electronics that we just don't need. I'm going through and getting rid of some of his things that he just doesn't need. :) Feel free to place an offer!!!
