Excerpt: I have been setting in the same office in a metal building for 15 years - sad I know - and this is the FIRST radio I have ever brought in that would pick up a radio signal of any kind. It not only picks up signals but picks up AM and FM, crystal clear. I have tried numerous antennas and signal boosters - nothing - until now. Awesome. I just ordered a second one for my garage just because it's such a great radio.
