CW-SSB OPERATION
ANTENNA
The
Receiver
must
have an antenna for proper
reception,
A length
of wire
10 feet long will
probably
give good reception
on the broadcast
band,
For
shortwave
listening,
a longer,
out-
door antenna should be used,

When tuning SSB (single side band) signals, tune
to the SSB station and then alternate between the
BAND
SPREAD
and
BFO
controls
for
the
clearest reception.
INSTALLATION
Generally,
the higher the antenna the better the
reception,
A tree
or pole may
be used as one
support
and your house
as the other support,
Insulators
must
be
used
at each
end
of the
antenna to separate
the antenna wire from the
support wire.
Lug 3 of the antenna terminal strip on the Re-
ceiver
should be grounded to a water pipe or to
a 6 to 8 feet long ground rod driven into the
earth,
To
connect
a dipole antenna to the Receiver,
connect
a short wire between
lugs 2 and 3 on
the
antenna
terminal
strip,
and
connect
the
two
lead-in
wires from
the dipole
antenna to
lugs
1 and 2 on the antenna terminal strip of
the Receiver, See Figure 26,
To connect
a folded
dipole antenna to the Re-
ceiver,
connect the two lead-in wires from the
antenna to lugs 2 and 3 on the antenna terminal
strip;
no wire
is used between
lugs 2 and 3,
See Figure 26,
