M Rear Window Antenna
The rear window antenna receives both
AM and FM signals.
CAUTION
When washing the inside rear window,
use a soft cloth dampened in lukewarm
water, gently wiping the antenna lines.
Use of glass cleaning products could
damage the antenna.
(With diversity tuning)
After FM signals have been received from
the rear window antennas, one of the
antennas is selected, and provides the best
FM reception. This is known as diversity
tuning. With this method you will be able
to enjoy the highest quality FM reception.

AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere. Therefore, they can reach
longer distances than FM signals. Because
of this, two stations may sometimes be
picked up on the same frequency at the
same time.

FM characteristics
An FM broadcast range is usually about
40—50 km (25—30 miles) from the
source. Because of extra coding needed to
break the sound into two channels, stereo
FM has even less range than monaural
(non-stereo) FM.
