ANTENNAS
@ FM antenna connections
FM broadcasts are characterized best by
their good sound quality. To enjoy sound
with a good quality, it is important to pick up
the signals reliably. Just like TV signals, FM
broadcast signals use ultra-short waves and
they are beamed directly, rather like light.
This means that the signal strength will
weaken in mountainous areas and between
high buildings. Choose the proper antenna
in accordance with the strength of the
signals in your area.
Using the accessory FM feeder antenna
The feeder antenna will sufficiently serve for
reception when the unit is located nearly the
transmitting antenna where the signals are
strong. Connect the accessory feeder anten-
na through the accessory 75—300 ohms
matching unit to the rear panel FM antenna
terminal (75 ohms), spread the two ends out
in the shape of a “T’’, find the position
which yields the optimum reception and at-
tach.
Using an outdoor FM antenna
If you live far away from the transmitting anten-
na or in an area where the signals are weakened
by obstacles in their path, such as steel-framed
buildings and other structures, erect an out-
door FM antenna. The reception will vary ac-
cording to the height, direction and location of
the outdoor antenna and so move the antenna
and find the optimum position.
When using the outdoor FM antenna and the
75-ohm coaxial cable to connect it to the tuner,
the connection method differs according to the
type of coaxial cable (3C-2V or 5C-2V) and so
connect as follows:
Shape the end of the coaxial cable, connect
it to the accessory 75 ohm FM antenna
adaptor, and then plug the adaptor into the
unit's coaxial cable terminal @4 .
