You need to be more specific. Where is the FM antenna on what? The FM antenna at a radio staion could be on a mountain. FM is called line of site transmission. Meaning, it shoots a beam , or wave, in a staight line to your antenna on your car or house. So, FM can be heard even if you are going through a tunnel, provided there are no mountains to block the signal. It is also called Frequency Modulation. AM is Amplitude Modulation. It is bounced up and down between the atmospere and the ground, until it hits your antenna. So, AM can even be heard if mountains block your signal. It simply bounces over and on top of them to your antenna. Where is your car?
