RANDOM LENGTH WIRE
ANTENNA INSTALLATION
For general broadcast and shortwave listening, an
outside random-length wire antenna can be used.
Figure 3 shows a typical random-length wire antenna
installation. The length of the wire may be from 30 to
100 feet. Attach and solder the lead-in to one end of
the antenna. Connect the other end of the lead-in wire
to the 50Ω screw terminal on the rear panel of your
receiver.
Generally, the higher the antenna is off the ground, the
better the reception. You may use a tree or a pole as
one support and your house as the other support. Use
insulators at each end of the antenna to separate the
antenna wire from the support wire. It is recom-
mended to install a lightning arrestor on the lead-in
wiring, especially if the antenna is outdoors and of
lengths exceeding approximately 30 feet.
* A Note About Grounding:
A ground wire is not necessary for proper reception
with this receiver when using the supplied 30 feet
piece of wire or when using resonant length type
antennas (dipole, vertical, or beam antennas). A
ground wire may improve reception, however, in some
cases, when using random length antennas.
TERMS TO KNOW
Antenna - A length of bare antenna wire.
Lead-in - A length of insulated wire. The length
depends upon the height of your antenna and the
location of your receiver.
Ground Wire - If used, connect a heavy wire from the
GND screw terminal on the rear panel of your
receiver to a cold water pipe or to a 6- to 8-feet long
piece of ground rod driven into the earth. The length
of your ground wire depends upon the distance
between your receiver and the grounding surface. (See
"A Note About Grounding" on this page.)
Insulators - A ceramic or glass type, approximately
2-1/2 inches long.
Ground rod - A 6-feet to 8-feet length, 3/8-inch diam-
eter conductive rod. NOTE: A ground rod is not
needed if you use an alternate ground, such as the cold
water pipe in your house.
Clamp - A device used to connect a ground wire to a
ground rod.
Lightning arrester - A device used to discharge lightning
to the ground, protecting electronic equipment.
For additional information on antennas, contact your
local library.
