The photo on the bottom is with the amplifier on. As you can see, signal strength has doubled, making it possible to quickly transfer data and make and receive calls that won't be dropped. As a test we drove to an area that has no AT&T service. This area is in a valley about 10 miles from the nearest tower. With the Wilson system on we got one bar of signal strength, which was enough to send and receive text message data. This ability to communicate could save your hide in the backcountry.
