FM Antennas
What type of antenna do you need?
Your need for a good antenna will depend on the receiving
conditions where you live; the further you are away from the
transmitter and the more obstacles (hills and tall buildings for
example) between you and the transmitter, the greater will he
your need for a good antenna. Remember that it is not good
enough just to receive a signal, especially if you are a serious
stereo listener. You need to receive a signal that is much
stronger than any unwanted electrical noise that might be
lurking around in your area. Furthermore, FM signals bounce
off large obstacles and cause you to receive the same program
from several directions at the same time, possibly out of
phase with one another. This gives distortion which you do
not want. Instead you need one strong, clear signal straight
from the transmitter and this may call for an elaborate,
directional antenna.
If in doubt you can consult your dealer who will probably be
more familiar with local receiving conditions than most
people. In any event you should install an antenna that is
better than the one that you think you can just manage with,
because under doubtful conditions a good antenna is just as
important as good loudspeakers.
Whether you need a simple antenna such as a folded dipole or
an elaborate multi-element array, the following tips will be
useful.
Antenna connections
This receiver is equipped with a balanced antenna input and
an unbalanced antenna input.
The 300 ohm balanced input terminals (socket on European
version) are intended for connection to a 300 ohm antenna via
a flat twin-lead balanced feeder having the same impedance.
The 75 ohm unbalanced input terminals (socket on European
version) are intended for connection to an antenna via a 75
ohm coaxial cable. The center conductor of the cable should
be connected to the terminal marked 75 ohms and the shield
should be connected to the chassis terminal just below.
If you have the European version you should fit the
appropriate plug.
