Optional outdoor FM antenna
Consult with your dealer or authorized service center about the
best method of selecting and erecting an outdoor FM antenna.
The choice of the feeder cable is also important. Flat ribbon-
shaped twin-lead cable performs well electrically, and is cheaper
and somewhat easier to handle when routing it through windows
and around rooms. Coaxial cable is more expensive, does a much
better job of minimizing interference, is less prone to the effects of
weather and close-by metal objects, and is nearly as good a signal
conductor as feeder cable, particularly for foam-type coaxial
cables. Coaxial cable is somewhat more difficult to install at the
point where the cable enters the building. If coaxial cable is
selected, make sure the antenna is designed to be used with that
type of cable.
Use a 75-ohm/300-ohm antenna adapter (not included) or a
75-ohm antenna adapter (not included) for connections.
Notes for FM antenna installation
● To minimize automobile ignition noise, locate the antenna as far
from heavy traffic as possible.
● Keep the feeder cable or coaxial cable as short as possible. Do
not bundle or roll up excess cable.
● The antenna should be at least two meters (6.6 feet) from
reinforced concrete walls or metal structures.
Optional outdoor AM antenna
In steel buildings or at a great distance from the transmitter, it
may be necessary to install an outside long wire antenna.
GND terminal
For maximum safety and minimum interference, connect the
GND terminal to a good earth ground. A good earth ground is a
metal stake driven into moist earth.
