Low Frequency Antenna

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2015 Jaguar XF, 2014 Jaguar XF, 2013 Jaguar XF, 2012 Jaguar XF, and 2011 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

Three Low Frequency (LF) antennae for the passive start system are positioned in specific locations in the vehicle; refer to Component Location graphic.

NOTE: On vehicles with the passive entry system, five additional antennae are used; one integrated into the rear bumper and one in each door handle assembly. These are only used by the passive entry system and have no function in the passive start system.

The keyless vehicle module transmits an LF signal via the antennae which is received by the Smart Key. The Smart Key then responds by transmitting a Radio Frequency (RF) signal which is received by the RF receiver and passed to the keyless vehicle module for authorization.
