How vehicle radio works
FM reception
AM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your vehicle. This sig
-
nal is then processed by the radio and
sent to your vehicle speakers.
However, in some cases the signal com
-
ing to your vehicle may not be strong
and clear.
This can be due to factors, such as the
distance from the radio station, close
-
ness of other strong radio stations or the
presence of buildings, bridges or other
large obstructions in the area.
AM reception
AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long distance, low frequency radio
waves can follow the curvature of the
earth rather than traveling straight. In
addition, they curve around obstructions
resulting in better signal coverage.
FM radio station
FM broadcasts are transmitted at high
frequencies and do not bend to follow
the earth's surface. Because of this, FM
broadcasts generally begin to fade
within short distances from the station.
Also, FM signals are easily affected by
buildings, mountains, and obstructions.
