Creation Description α) [Technical Field to which the New Type belongs] This creation relates to an automobile digital TV antenna adapter, especially an adapter structure that can take into consideration the radio listening and the quality of digital TV reception. [Previous technology] Press; general cars are equipped with a broadcasting antenna (AM / FM), which can be divided into automatic telescopic, hand-drawn or hidden, etc., but if you install a digital TV in the car, you need to add another When installing a set of upright antennas, there are the following shortcomings in the open-air line outside this addition: 1 · When washing the car, the installed antenna must be taken into the car to avoid cuts and damage, which is very troublesome. 2 · The antenna that protrudes from the inside of the car needs to bypass the door and then be adsorbed on the roof, which will cause the rubber between the door and the car body to form a groove, resulting in water leakage in the car. 3 · When the vehicle is parked on the side of the road, if you forget to remove the antenna, the antenna will be easily stolen. In serious cases, the receiver, TV and audio in the car will be stolen. 4 · There are fixed antennas on the roof of the original vehicle. If one or two antennas are added, the roof will be too cluttered, which will affect the view of the car body. [New content] The main purpose of this creation is to provide a car digital TV antenna adapter so that the car can take into account the quality of listening and receiving of radio and digital TV without installing an antenna.
