1. Check for continuity from
the antenna, through the
cable:
a. Remove the FM/DHF
connection from the
ITU.
b. Using an Ohmmeter,
check the resistance
between the center
conductor (pin) in the
cable and the chrome
base on the antenna
near the split lock
washer.
You should get a reading of 0.5 ohms or less.
c. If you received a reading of 0.5 ohms or
less, skip to step 2.
d. If you did not get a reading of 0.5 ohms
or less in step a, remove the other end of
the cable from the antenna connector.
Check the resistance between the center
conductor of the antenna connector and
the chrome base on the antenna near the
split lock washer.
You should get a reading of 0.5 ohms or less.
e. If
you did receive a reading of 0.5 ohms
or less, the connector is good. Replace
the coax cable. If the reading was more
than 0.5 ohms, replace the antenna
connector.
