The History of Car Satellite TV Antenna
The role of the various types of radio equipment to be performed is different, but the role of the Car Satellite TV Antenna in the equipment is basically the same. Any radio equipment is transmitted through radio waves, so there must be a device that can radiate or receive electromagnetic waves. Therefore, the first role of the Car Satellite TV Antenna is to radiate and receive electromagnetic waves. Of course, things that can radiate or receive electromagnetic waves are not necessarily used as a satellite satellite TV antenna.
The energy of the electromagnetic wave is radiated from the transmitting satellite satellite television antenna and will propagate forward in all directions of the surface. If a wire is placed in the alternating electromagnetic field, the alternating voltage - electromotive force is excited at both ends of the wire due to the magnetic field cutting of the wire. The frequency is the same as the frequency of the transmission. If the wire is connected to the receiver via a feeder line, the current of the modulated signal can be obtained in the receiver.
With the rapid development of wireless communication and the increasing demand for information, modern cars require more and more wireless service facilities, especially luxury cars. Car Satellite TV Antenna manufacturers not only need a standard AM FM radio reception system, but also need TV reception, keyless entry, remote control, satellite navigation, mobile phones and future digital radio. Thus, the radio systems of these service facilities were generated, and the car satellite television antenna served as a front-end equipment for the radio system and played a vital role in the whole system.
   Users have a radio, especially the FM radio, in order to ensure a good listening effect, will be equipped with car radio satellite TV antenna, some cars from the appearance will be able to see the Car Satellite TV Antenna, and some car appearance Do not see the Car Satellite TV Antenna. So do not see the Car Satellite TV Antenna by car to receive broadcast signal?
Automotive industry experts: In fact, all cars will have a Car Satellite TV Antenna, but quietly hidden up, then the car can not see the Car Satellite TV Antenna hidden in what place? It is hidden in the rear window of the car, take a closer look at your car rear window glass has a thin line, those printed on the glass is the fine line of the car radio satellite TV antenna. This kind of Car Satellite TV Antenna called active rear window Car Satellite TV Antenna system, is a 90 years developed a car Car Satellite TV Antenna system, the use of automotive rear window defrosting printed circuit patterns, coupled with specially designed car satellites The TV antenna amplifier and its accessories, while retaining its defrost function, make it an active receiving unit for the AM / FM signal. The advantage of this Car Satellite TV Antenna is that superior AM / FM reception performance, with very good durability, to prevent high-speed traffic when the wind noise, to prevent theft and car wash damage, but also put an end pole or automatic car satellite Insulation of TV Antenna.
Car Satellite TV Antenna manufacturers are we often see the Car Satellite TV Antenna antenna tail Car Satellite TV Antenna, accept or strengthen the receiving signal, GPS Car Satellite TV Antenna is usually a small black block, paste in the automotive dashboard and other fields. Some cars are using a printed circuit Car Satellite TV Antenna hidden above the front windshield, by contrast, a lot of pretty.
Why i think it is the same car as the Car Satellite TV Antenna?
Mainly speaking is the car's external Car Satellite TV Antenna, that is, Car Satellite TV Antenna. Car Satellite TV Antenna can refer to mobile radio, mobile radio is a built-in Car Satellite TV Antenna, you can also see the Car Satellite TV Antenna received the signal, however, if you go to the more remote the signal is not very stable, the acceptance is not obvious , The external Car Satellite TV Antenna can enhance the signal impact.
Many countries in the world, people involved and hidden amateur radio, like to participate in the game, they wear uniforms, they feel the station area. Such activities have different names in different places, such as fox hunting, catching rabbits, amateurting directions, or simply asking for stations, in North America, most people drive to the station, but now more and more popular.
