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.)

Mounting

■
CAUTION: Mount the AT-141 in a horizontal position
or in a vertical position with the antenna terminal up.

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-141.
