DIRECT
WAVE
A home receiver can catch weak FM stereo signals
through the use of a tall, directional or ultra-sensitive
antenna. In a moving vehicle, the area for good
reception is limited because of varying conditions
encountered while driving, including the types and
heights of broadcast antenna structures, signal strength,
engine noise, etc. For best reception with manual
antenna, extend the antenna mast as far as possible.
The reflection characteristics of FM waves cause
another problem called multipath–FM wave signals
reflecting off of buildings, mountains, etc. When the
antenna receives direct and reflected waves at the
same time, distortion of sound in the treble range often
occurs, such as static or harsh-sounding voices. THIS
IS NOT A TUNER PROBLEM. Only moving to another
area with a clearer signal path can remedy the situation.
