B3: CHECK THE ANTENNA CORE RESISTANCE
1 Remove the antenna mast.
2 Using a digital multimeter, measure the
resistance between the center pin on the
antenna connector and the antenna mast
screw thread
• Is the resistance less than 1 ohms?
Yes
GO TO B5
No
CHECK the in-line connectors. INSTALL a
new antenna cable.
B4: CHECK THE ANTENNA BASE CONNECTOR RESISTANCE
