I live in a very rural area north of LA & have alwsays had problems with FM reception. I purchased a Magnum Dynalab ST-2FM antenna after trying several others & I must say it works awsome. The key was not to just put it on the roof somewhere. I actually got outside on the cell phone with my wife near the tuner on her phone. I moved all around the roof area until she gave me the "best signal" sign. The placement was very critical. Believe it or not, the best spot was on the side of the house & not on the peak. Had I not tested the reception this way I would have had little or no increace in reception. Good luck with yours.
