INSTALLATION
ELECTRIC SERVICE
CONSI DERATIONS
The
Receiver
will
operate
on either
120 Vac
or
24O
Vac, but
it
must be
wired
specifically
for
the voltage
to
be
used. Full
instructions
are
included
in "Step-by-Step Assembly."
ANTENNA INSTALLATION
The
Receiver
must
have
an
antenna connected
for
proper
shortwave reception.
The
built-in
antenna
is
for
broadcast
reception only.
For general broadcast and shortwave listening,
a
long-wire
outside antenna
is
suggested.
A
typical longwire
antenna
installation
is
shown
in
Figure 3. The length of the antenna
wire may be from 50
to
100
feet
long.
The lead-in wire
should
be
attached and
soldered
to
one
end
of the
antenna.
The other
end
of the
lead-in
wire
is
connected
to
the ANT
terminal on the rear
of the
Receiver.
Generally,
the
higher the antenna
the better the
reception"
A
tree
or pole may
be used as
one support and
your
houseas
the other support.
Insulators
must
be used
at
each
end
of
the
antenna
to
separate
the
antenna
wire
from
the support
wire.
The
GND terminal
on the
rear
of the
Receiver
should
be
grounded
to
a
water pipe or to
a
6
or
8
foot
long
ground
rod
driven
into
the earth.

A dipole
antenna may be used
for optimum reception
on
the
shortwave band. This
type
of
antenna
is
directional and
is
designed
to
receive
a
narrow band
of
the
shortwave
frequencies.
lt
is
suggested
you
check an
ARRL
Handbook*
or
an
Antenna Flandbook
for
the proper
dipole
antenna
length
needed
for
the shortwave frequencies
of
interest.
The
two
lead-in wires
from a
dipole antenna should
be
connected
to
the
ANT
and GND
terminals
on
the rear of the
Receiver.
