The listing, Phone Antennas Antenna Booster.. has ended.
The internal antenna booster works like a dish on a satellite to capture and emit a stronger signal. By placing the internal antenna behind the fixed antenna of the phone you increase the surface area for sending and receiving messages. Allowing for increased signal strength eliminating dropped calls and reducing static interference. This antenna is easy to install. Just slip it underneath the phone's battery, and enjoy clear, enhanced, static-free reception.
