What is an FM Radio Transmitter?


FM broadcast transmitter is a kind of electronic device that transmits radio waves. It converts audio signals to radio signals and transmits radio signals with the help of an FM antenna. Its transmitting power can reach as low as 0.1 watts and as high as tens of thousands of watts. As the transmitting power would affect the coverage and signal penetration capability of the FM broadcast transmitter.


Therefore, FM radio transmitters with different transmitting power will be applied in different applications based on different needs. It can be said that FM radio transmitter is the core of FM broadcasting. So, what specific applications are FM broadcast transmitters used in?


The Applications of FM Radio Transmitters


As the core equipment in transmitting audio signals, the FM broadcast transmitter can be used in any applications that need to transmit sound. We will provide you with a list of applications that may use FM broadcast transmitters here, and focus on several of them. 

Drive-in Broadcasting Services

In the Drive-in Broadcasting Services, there are typically drive-in movie theater, drive-in church, and drive-in concert, etc. It allows people to watch movies, worship, and go to concerts as usual without contacting others closely.


Here, the event organizer will prepare a computer or other external equipment to input the audio signals into the FM broadcast transmitter. Then FM radio transmitter would transform the audio signals into radio signals, and transmit them through the FM antenna. And the listeners can receive the radios signals and listen to the radio programs through the car radios or MP3 players, etc.

Christmas Light Display Broadcasting

In a perfect Christmas light display, there should be not only Christmas lights, but also matched music. Not only the audience viewing in the light show, but also passers-by and cars passing by can watch the beautiful lights, listen to Christmas music, and enjoy the nice Christmas Eve.


Here, the assistance of an FM radio transmitter is indispensable. You can put your selected Christmas songs into your USB flash drive or computer, and then connect them to the FM radio transmitter with the audio cable. After connecting the FM antenna well and turning on the power, people around can listen to Christmas music. At the same time, you can also connect the light control box and FM radio transmitter with the audio cable to make your Christmas lights flash as your music rhythm.

FM Radio Stations

For broadcasters or large radio stations, both need FM radio stations to broadcast the recorded programs. FM radio stations cover the radio programs signals to a city or a larger area, the audience within the coverage can listen to the radio programs with FM radios.


FM radio stations are equipped with high-power FM broadcast transmitters (up to thousands of watts or tens of thousands of watts). The radio station staff will input the audio signals into the FM radio transmitter through the audio cable. The audio signals will be transformed into radio signals and transmitted to every corner of the city through the FM antenna. Then the public can listen to the radio programs of the broadcasters.

Education Broadcasting

When we are students, even during class hours, it is hard to avoid being disturbed by the noise outside the classroom. But FM broadcast transmitter solves the problem.


In the field of education, FM radio transmitter still takes the role of audio transmission. But its more important role is to reduce noise. If the content of classes is broadcast by FM broadcast transmitters, and the students listen to the classes through FM receivers like MP3 players, most of the noise will be isolated, and the sound will be clearer. Similarly, for a student with hearing impairment, if he uses a hearing aid with FM receiving function, it will greatly help him live a normal life. 

Other Applications

In addition to these four broadcast applications, FM broadcast transmitters can also be used in school broadcasting, supermarket broadcasting, farm broadcasting, factory notice, scenic spot broadcasting, enterprise conference broadcasting, advertising, music programs, News programs, outdoor live broadcast, live drama production, correctional facilities, real estate broadcasting, dealer broadcasting, etc.
