ANTENNA
AM and AM/FM Models
All antennas must have good ground to eliminate
static noises. The mast of the antenna is not grounded
except through the radio. The base of the antenna is
grounded to the vehicle sheet metal. The coaxial shield
(the wire mesh) surrounding the center conductor wire
of the antenna lead-in cable is grounded to the radio and
the antenna base.
Tests
There are three antenna tests to be made with the use
of an ohmmeter:
• Mast to ground
• Tip of mast to tip of conductor
• Body ground to battery ground
Refer to figure 3V-18.
