Integrated Antenna Trouble
Has anyone ever had problems with the integrated antenna? I have a 2001 C5 with an aftermarket stereo and the antenna will not pick up. The signal actually gets worse when the wire is attached.
Thanks for any help

The Corvette Coupe features a diversity antenna system designed to deliver the best radio signal reception possible.
Two antennas are used to form a diversity system. The primary antenna is attached to the rear lift window similar to a defogger grid. This antenna is used to receive both AM and FM signals. The secondary antenna is attached to the windshield in the same manner as the primary antenna. This antenna is used to receive only FM (diversity) signals. The antenna reception signals are sorted by a reception processing module. The module then sends the clearest, strongest signal to the radio control. Have you checked the antenna module? It is located at the base of the drivers side B pillar. There is also an antenna buffer that is located above the rear roof bow trim panel. Have you checked the resistance to ground from the antenna center conductor and from the antenna ground conductor? Do you have continuity from the radio end of the antenna to the antenna module?
