Query: No improvement at all in my reception

The best place in my house for reception is the third floor attic of my townhouse. I receive 1/2 bar at best on the ground floor where the line often goes dead, but 1.5 bars and consistent reception in the attic.So, I set this up in my attic as per the instuctions, and extended the line downstairs, but there absolutely was no improvement in my reception anywhere in the room. Tried several adjustments of location, but it still didn't work.They took it back as a return with no problem. I don't know if the one I received was defective, or if it just doesn't work in the conditions in my townhouse.
