My house is a Faraday cage - all steel construction & wrapped in foil insulation - so I get absolutely no radio reception whatsoever inside.  I mounted this on my defunct satellite antenna mast and used the existing coax that runs into the house.  Antenna is mounted at chest height & aimed at the cell tower.  Reception on phone is 2 bars at this location.  After hooking up I get 4 (max) bars on the phone in all rooms in the house.  This contraption will pay for itself in no time since I no longer need a land line.
