Does your apt. have a balcony that is in the direction of west north west?? Or can see in the direction of west north west from the balcony. Are there any small satellite dishes on the out side of the building?? There is a Tv antenna that looks like a small dish , AntennaCraft HDX1000 ,

Strong signal reflections - multipath - over load the digital tuner. The variable attenuator reduces the strength of the signal so the digital tuner can process the signal.
