Waterproofing the antenna connection

■
CAUTION: If you skip the following steps, moisture
will get into the connector, and this could damage
the antenna tuner.
q Cut off just the top of the weatherproof cap, and
pass the antenna wire through the cap.
w Insert the antenna wire into the opening of the
crimp-on wire terminal.
• Crimp or solder the antenna wire.
Crimp
e Put the crimp-on wire terminal, star washer, and
wing nut on the base nut, in that order, then,
tighten the wing nut.
• Make sure the base nut is tightened firmly, before you
tighten the wing nut. (See the Fig.1 to the right.)
• Carefully bend the wire terminal up, after you tighten
the wing nut. (See the Fig.2 to the right.)

Solder Solder
NOTE: Use a soldering iron with enough heating
power to securely solder the ground braid and
body. Otherwise the connection may be loose, and
communication trouble may occur.
r Screw the coupling ring onto the connector body.
Fig.1
r Place the weatherproof cap over as much of the
insulator as possible.
• How far down it will go depends on the height of the
wing nut.
t Start wrapping the rubber vulcanizing tape at the
bottom of the insulator, then the weatherproof cap
and finally the antenna wire to prevent water seep-
ing.
• Wrap electrical tape* over the rubber vulcanizing tape
to secure waterproofing.
* The electrical tape is not supplied with the AT-140.
