Where is the external RF Cadillac antenna located, and what is the coax antenna responsible for?

The external (radio frequency) RF antenna is located in the back glass just under the rear defrost grid.

What is the use of the Cadillac console active antenna?

The console active antenna is responsible for transmitting a low frequency challenge to the transmitter in the event that the transmitter does not respond to the headliner console passive antennas while starting. It is also used during transmitter programming events. The keyless entry console active antenna is located in the center console. The console active antenna which is controlled by the RCDLR has a small pocket next to it where the transmitter can be inserted if its battery is dead, weak, or if there is an interruption in the RF signal. If properly inserted in the pocket with the buttons facing forward, the active antenna should always cause the transmitter to respond properly.
