6 Buying Tips for the Best Low Power FM Transmitter


Learning technology parameters is helpful for us when choosing the best low power FM transmitter. However, each FM radio transmitter has too many parameters, and which one should we focus on? Luckily, FMUSER summarizes 6 main tips for choosing the best low power FM transmitter for drive-in.

Full Range Frequency

An FM radio transmitter with full range frequency can provide more channels for choices and help you avoid FM signals interference. Why not choose the FM transmitters with a full range of frequency? Once you are aware that there are signal interference around, you can adjust the FM transmitter and find the unused frequency to transmit clear FM signals outward.

Note: In general, there are basically 3 types of FM frequency range all over the world:


  • Standard FM broadcast band: 87.5 - 108.0 MHz
  • FM frequency band used in Japan: 76.0 - 95.0 MHz
  • ORIT band: 65.8 - 74.0 MHz 

Top Sound Quality

Sound quality really matters because it determines the listening experience. Better sound quality can help you attracts more listeners and grow your business. So you need to learn the definition of audio stereo separation and other audio parameters, etc.. In general, the audio stereo separation of 40 dB and SNR of 65 dB are acceptable.

Abundant Transmitting Power

An FM radio transmitter with abundant transmitting power can ensure you can provide broadcasting services to all the listeners. The Effective Radiated Power (ERP) determines how many areas you can transmit. What you should understand is that ERP is not equal to transmitting power, and it depends on the transmitting power and the performance of the FM broadcast antenna. It is advised that you choose a low power FM transmitter with transmitting power higher than your expectation, then you could ensure you have enough ERP.

Budget Price

A low power FM transmitter with a budget price is our ultimate target. But it doesn't mean that you have to give up some important features of the FM radio transmitter. Most importantly, you should choose a low power FM transmitter that fits your drive-in business' budget without compromising its quality, integrity, and functionality.

Easy Operation

Easy operation can reduce a lot of annoying troubles for you. For example, reasonably designed buttons can help you easily adjust the FM broadcast transmitter and avoid misoperation as much as possible. And if there is a clear LCD screen equipped on it, you can learn about the status of the FM broadcast transmitter directly and know the problems in time.

Complete Safe Protection Functions

The safety protection function can shut down the machine in time in case of machine failure to avoid further loss. The safety protection function is what you can't ignore when choosing the best FM radio transmitter. It should be able to start the protection mechanism in time in case of a harsh environment, such as overheating, supercooling, water, etc.

In short, we need to focus on the 6 points: full frequency range, top sound quality, abundant transmitting power, easy operation, budget prices and complete safety protection functions.
