For 20 years I have climbed various homes, office buildings, put antennae up above the roof, in the attic, tried every fancy FM antenna that is sold and bought high end receivers all the while wondering why in the hll my car stereo gets my favorite stations but my house and office cannot. Well shame on me, with just the tiny wire FM antenna my new RS81 is tuning in stations from Rockford, Madison, Chicago, Champaign and DeKalb !!! I feel like the luckiest boy on Christmas morning! There is not one ounce of regret in this purchase price. I double dare you to buy this!
