n 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 Solder
e Put the star washer, crimp-on wire terminal, 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.)

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 bot-
tom of the insulator, then the weatherproof cap and
finally the antenna wire to prevent water seeping.
• Wrap electrical tape* over the rubber vulcanizing
tape to secure waterproofing.
* The electrical tape is not supplied with the AT-140.
