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.
