That doesn't prove anything. That's like saying your satellitte receiver at home must only use one antenna as there is only 1 wire to the receiver. In fact, some have as many as 4 "antenna's" - actually LNB's that get combined at a switch that controls the traffic - so to speak then feeds via a single line.
On the C5 coupe, there is an antenna combiner under the plastic trim of the "B" pillar or hoop where the AM (in the back window) and the FM (on the front glass "combine" and one coax feeds both signals to a single cable that connects on the rear of the receiver..
