Cable, Antenna: Operation

The coaxial antenna cables each contain a center copper conductor covered by an inner dielectric insulator. The dielectric insulator is then covered by a braided or woven copper shield, which is then covered by a protective outer plastic sheath. The center conductor carries the Radio Frequency (RF) signals from the antenna module or antenna to the receiver, while the braided copper shield is grounded through the radio chassis at one end and either the antenna module or the antenna base at the other end to help to protect the conductor from RF signal interference.

For more information on testing the coaxial cables using the (special tool #9977-6, Kit, Radio Antenna Diagnostic) and perform the procedure for. Refer to DIAGNOSIS AND TESTING .Poor or No AM/FM Audio Reception  or Poor or No Satellite Audio Reception  as appropriate.
