摘要： A lift system includes at least one travel rail mounted in a shaft, and a lift car having a chassis that is disposed on and movable along the travel rail in a travel direction. Also mounted in the shaft is a slotted hollow conductor having a slot defined therein extending in the travel direction. A holding arrangement that holds a cabin antenna extending therefrom is further coupled to, and movable with, the lift car in the travel direction, such that the cabin antenna protrudes into an interior of the slotted hollow conductor through the slot, and is movable along the length of the slot as the car moves in the travel direction. An antenna guide extends parallel to the travel direction of the lift car and is configured to guide the cabin antenna in the slot of the slotted hollow conductor.
