Hello everyone. I am a mechanical engineer but I have a question which I hope someone can provide me some info. I was interested to know whether it is possible to block signals by creating a magnetic field or not. I'm asking this question because some people live in places which have a lot of noise on TV due to a nearby power station etc. Is there any way to block these terrestrial interferences by making some kind of magnetic field and get a clear satellite picture? I also want to be able to detect the approximate location of this noise. What do you reckon for this one? I appreciate if someone can point me in the right direction.
