AM antenna is used for AM(Amplitude Modulated) wave and FM antenna is used for FM(Frequency Modulated) wave transmission/reception. AM stands for Amplitude Modulation while FM stands for Frequency modulation.

Can you use an AM antenna for FM?
While you can use AM antennas for amplitude modulated (AM) mediumwave reception/transmission, the FM antenna works for frequency modulated (FM) wave transmission/reception. So, no, an AM loop antennas will not work for FM.
Is there a difference between AM and FM antenna?
In AM, a single wavelength is 984 feet for a 1MHz signal. In FM, one wavelength is about 12 feet. Thus, the popular quarter-wave antenna often used for AM might be 246 feet high, and the FM antenna elements would be only around three or six feet long, depending on the antenna design.
Is FM better quality than AM?
"FM, which stands for Frequency Modulation, has better sound quality due to higher bandwidth. Also, the way the audio is encoded for FM makes it less sensitive to interference from electrical activity from storms or electrical devices than AM.
Why is FM reception is better than AM reception?
Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static. With an FM broadcast, slight changes in amplitude don't matter -- since the audio signal is conveyed through changes in frequency, the FM receiver can just ignore changes in amplitude.
