FM Radio is an audio-only broadcast medium with a high frequency-range. The advantage of FM over AM includes a much clearer signal and reception in stereo separation. The disadvantage is FM signals require a substantial antennae to receive a signal, especially from distant transmitters. Most FM receivers have a built-in antennae in the power cord, but using an external antennae, such as those available for broadcast television, can dramatically improve signal reception.
