Antenna
6. Antenna
A: INSPECTION
Measure the resistance between antenna terminal
and each antenna wire.
If an antenna wire is OK, resistance will be less
than 1 Ω. If an antenna wire is broken, the resis-
tance will be more than 1 MΩ.
NOTE:
When checking the continuity, wind a piece of alu-
minum foil around the tip of tester probe and press
aluminum foil against wire with your finger.
To locate the broken point, move the probe along
antenna wire.
B: REPAIR
1) Clean the antenna wire and surrounding area
with a cloth dampened by alcohol.
2) Paste a thin masking film on the glass along bro-
ken wire.3) Deposit conductive silver composition (DU-
PONT No. 4817) on the broken portion with a draw-
ing pen.
4) Dry out the deposited portion.
5) After repair has been completed, measure the
resistance in repaired wire.
