History of Motor Homes Antenna
Although the various tasks to be performed by radio equipment are different, the role of the Motor Homes 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 Motor Homes Antenna is to radiate and receive electromagnetic waves. Of course, something that can radiate or receive electromagnetic waves is not necessarily used as an Motor Homes Antenna.
After the energy of the electromagnetic wave is radiated from the transmitting Motor Homes Antenna, it will propagate forward in all directions of the ground 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 communications and the increasing demand for information, modern cars require more and more wireless service facilities, especially luxury cars. Motor Homes 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 Motor Homes Antenna served as a front-end equipment for the radio system and played a vital role in the overall system.
Motor Homes Antenna manufacturers are we often see the radio Motor Homes Antenna tail Motor Homes Antenna, accept or strengthen the receiving signal, GPS Motor Homes Antenna is usually a small black block, paste in the automotive dashboard and other fields. Some cars are using printed circuit Motor Homes Antennas hidden above the front windshield, by contrast, a lot of pretty.
Why i think it is the same Motor Homes Antenna?
Mainly speaking is the car's external Motor Homes Antenna, the radio Motor Homes Antenna. Motor Homes Antenna can refer to mobile radio, mobile radio is a built-in Motor Homes Antenna, you can also see the Motor Homes Antenna received the signal, however, if you go to a more remote place the signal is not very stable, the acceptance effect is not obvious, the external Motor Homes 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.
The Motor Homes Antenna of a Motor Homes Antenna manufacturer is simply a converter that converts a guided wave into an electromagnetic wave, or vice versa, so it can be used in a radio device to transmit or receive electromagnetic waves. Therefore, it is reversible for the Motor Homes Antenna, the same Motor Homes Antenna can be used as a transmitting Motor Homes Antenna, can also be used as a receiving Motor Homes Antenna.
If the wavelength is divided by the operating wavelength, the Motor Homes Antenna can be divided into ultra long wave Motor Homes Antenna, longwave Motor Homes Antenna, medium wave Motor Homes Antenna, shortwave Motor Homes Antenna, ultrashort wave Motor Homes Antenna and microwave Motor Homes Antenna.
Resonant frequency: it is related to the electrical length of the Motor Homes Antenna, and the electrical length is expressed by the wavelength. Gain: refers to the ratio of the intensity of the radiation pattern to the intensity of the reference Motor Homes Antenna, which is mainly related to "aperture" and "radiation pattern". Bandwidth: refers to the frequency range in which it works effectively, usually centered on the resonant frequency.
