This 4G booster works perfectly.  It was installed in a cabin that we just purchased.  We bought a cabin to get away from our cell phones--not to boost their signals, so we took it out and are selling it.  The SignalBoost works perfectly and comes with everything you need to install it.  You might need more cable, depending on how far away you want the booster from the antenna.  Shipping is free and via USPS Priority Mail.
