TV Antenna Amplifiers (If Equipped)
WARNING: This page is about a different car, the 2009 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
The TV antenna amplifiers are powered by the TV antenna module through the same coaxial cable used to carry their signals to the TV antenna module. They are attached to 2 of the 4 TV antenna trace patterns in the rear window glass.
