FM ANTENNA |
For best reception of FM broadcasts, select an FM antenna
with the best characteristics for the area in which the unit
is to be used.
Wi Included antenna
The included antenna is easy to install and is suggested for
use until a permanent antenna is installed especially for
FM. An antenna especially for FM should be installed in
order to obtain the best reception characteristics of which
this unit is capable.
I Antenna exclusively for FM reception
1) Selection
1. In areas where very strong broadcast signals are re-
ceived (where the transmitting antenna can be seen),
use an outside antenna with 3-~5 elements.
Where signals are strong: an antenna
with 3~5 elements
2. in areas where weak broadcast signals are received
(in mountainous regions or between tall buildings),
use an outside antenna with 5 elements or more.
Where signals are weak: an antenna with 5
elements or more
Note:
Consult with your dealer for detailed advice concerning
the number of elements the antenna should have.
2) Connection wire from the antenna
To obtain the best performance of which this unit Is
capable,
the
cable
used
to
connect
this
unit
with
the
special antenna for FM reception should be 75-ohm
coaxial cable (type 5C-2V or 3C-2V) which resists the
effects of external noise.
3) Impedance matching
lf it is impossible to make a direct connection with
75-ohm coaxial cable from the antenna, a matching
transformer should be installed, as close to the antenna
itself as possible.
