This 12v duel-band cellular amplifier does exactly what it is supposed to do. I installed it in my motor home to increase the range, speed, and reliability of my Verizon 3G Sierra broad band air card, which I use with a CDMA wireless router to provide internet coverage throught the RV. I mounted a Wilson Trucker’s Antenna (see link below) on the roof of the motor home, and routed the antenna cable to this amplifier. I’m amazed at how much better and reliable my CDMA data reception is. The card almost always works at peak rated performance limits when connected to this Wilson Amplifer and the Wilson Antenna. I’m extremely happy with this set-up and would recommend it to anyone, especially other RV’ers.
