Antenna mounted in vehicle has detection mechanism to generate detection signal for detecting whether antenna mast is coupled to antenna base

摘要

The antenna (14) has an antenna base (18) in which a detection mechanism is removably coupled. The detection mechanism (24) such as radio frequency (RF) device generates a detection signal for detecting whether an antenna mast is coupled to the antenna base. The RF device has a plunger that is partially arranged within a plunger main portion, and that is movable within the plunger main portion between a first position and a second position.
