Multi path reections

FM waves, like light waves, travel in a straight direction unless reected

o objects in their path. Because of this, two sets of waves reach your

antenna from the FM station; those that have traveled directly to the

antenna, and those that have been reected o buildings or mountains.

When the antenna receives both kinds of signals, the two interfere with

each other and result in distorted sound and poor separation. This phe-

nomenon is called "multi path reection". To reduce this problem, select

an antenna with good directivity and place it in the best location with

strong reception.
