Window Antenna Wire Repair
NOTE: To make an effective repair, the broken section
must be no longer than one inch.
1. Lightly rub the area around the broken section with
fine steel wool, then clean it with alcohol.
2. Carefully mask above and below the broken portion
of the window antenna wire with cellophane tape.
CELLOPHANETAPE
Using a small brush, apply a heavy coat of silver
conductive paint extending about 1/8" on both
sides of the break, Allow 30 minutes to dry.
NOTE| Thoroughly mix the paint betore use.
Check for continuity in the repaired wire.
Apply a second coat of paint in the same way. Let it
dry three hours before removing the tape.
