The embodiment of the utility model discloses an antenna unit, as shown in fig. 1 and fig. 2, the antenna unit includes an antenna 10, an antenna connector 30 and a sealing member 40.

Specifically, the antenna 10 is a flexible cable, and the conducting wire 20 is connected to the antenna 10, and the conducting wire 20 is used for transmitting signals received by the antenna 10. The antenna connector 30 is connected to the antenna 10 by the wire 20, and the antenna connector 30 is used for connecting an antenna amplifier. The lead 20 is sleeved with a sealing element 40, and the sealing element 40 is used for sealing the position where the lead 20 penetrates through the vehicle body sheet metal.

As an embodiment of the present application, the flexible cable is a FLRY-B cable.

As an embodiment of the present application, the antenna 10 may include a plurality of cables. Taking two flexible cables as an example, as shown in fig. 1, one end of each of the two flexible cables is a free end, and the other end of each of the two flexible cables is a non-free end and is connected to the conducting wire 20. When the antenna 10 adopts two cables, in the process of connecting with the lead 20, the non-free ends of the two flexible cables are directly stripped and then connected with the lead 20; if the antenna 10 is a cable, when the antenna 10 is connected to the conducting wire 20, the cable needs to be stripped from the middle of the cable and then connected to the conducting wire 20, which complicates the process. Therefore, the wire stripping of the end portions of the two cables is more convenient and faster, and therefore, the antenna 10 adopts two or more cables, the processing procedure for connecting the antenna 10 and the lead 20 is simplified, and the processing efficiency is improved.

Specifically, the antenna 10, when having two free ends, may be used to receive AM/FM signals, enabling the vehicle to implement AM/FM functionality. One way of implementing the antenna 10 having two free ends for receiving two signals is that the antenna 10 comprises a cable, the middle of which is connected to the conducting wire 20, and the two ends are used for receiving signals. In another implementation, the antenna 10 includes two cables, one end of each cable is connected to a conductive wire and the other end is a free end. Specifically, the length of the flex cable is determined by the frequency of the signal it is intended to receive.
