Rod antenna for use on vehicle roof, has outer shell with outer shell regions that are made of different plastics, where elasticity modulus of plastics of one region is greater than that of plastics of other two regions

摘要

The antenna (1) has an attachment region (2), and an elongated radiator region (3) protruding from the region (2). The region (2) has a threaded part (7) that is connected with an elastically deformable connecting part and a radiator, which is connected with the connecting part. An outer shell has outer shell regions (4-6) that are made of different plastics. The region (5) partially extends over the connecting part, where an elasticity modulus of plastics of the region (5) is greater than that of the plastics of the regions (4, 6), where the shell has a coating of chromium or color layers.
