To the contrary AM reception works best with the antenna as high as possible but FM (frequency modulation) works best at 31" to match the constant height of the transmission wave. Having the antenna too high while listening to FM creates flutter-echo type problems.
This is why all cars starting in the 70's switched to shorter antennas when AM/FM radios became the norm.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
