Many changes happened in the past two years because of the COVID-19 pandemic. Many people are hesitant to be crammed into a single hall with everyone close together. But at the same time, listening to the Word of God on a Sunday is vital for your spiritual health. 

With all these in mind, churches have adapted during this challenging time. They moved to the digital space and offered online services. Fellowship occupied virtual hangout spaces. Gospel sharing became widespread in social media. 

With the need for innovation and creativity, some churches found a way to conduct services while maintaining social distancing through drive-in audio streaming. Churches can do this with the use of FM transmitters!

Here are the best FM Transmitters for Church we will be reviewing:

What are FM transmitters for Church?

FM transmitter for churches is a device that converts an audio output. After which it broadcasts it into an FM frequency. Broadcasters use particular frequencies among the FM bandwidth for audio programming. FM transmitters for churches usually have a low power range. This coverage is enough to cater to their vicinity. Through FM transmitters, churches have served their congregation during this time. 

Why Use an FM transmitter for Church?

The use of an FM transmitter for churches has allowed continuous church gatherings despite the worldwide lockdowns and quarantine protocols. Through drive-in services, churches deliver sermons through FM frequency broadcast. This setup is possible while church members are in their cars’ confines or stationary in the parking lot. Churches can also use FM transmitters during services located at other outdoor venues. This method assures that church members keep social distancing protocols while still listening to the Word of God. 

FM transmitters provide easy and affordable technology for churches in this global pandemic. Churches can still hold events, prayer and worship gatherings, and Sunday services.

How to Set Up an FM Transmitter for Church?

FM transmitters have different styles. Yet, all transmitters have fundamental parts. These include receiving port, cable connector, transmission, and sometimes an antenna.

Usually, the first thing that FM transmitters do is look for and select an available FM frequency. The next thing to do is plug the FM transmitter into the device containing the audio you want to share. Some people use music players or smartphones. Usually, the audio is the Sunday sermon or prayer devotions. The FM transmitter then broadcasts the audio to each church member’s car radio. This broadcast is through the identified channel. The congregation then can listen to the audio sent out.

With a limited range, it is best for the speaker or the pastor to position himself at the center of the parking lot. It is also possible in the middle of any other outdoor venue. This setup will entail other tools like extension cords and audio cables. A low-power device will result in audio and frequency difficulties if the speaker is inside the church hall.

Guideline and Rules in Using an FM Transmitter for Church

Setting up an FM transmitter for churches is easy. But it is challenging to broadcast into an FM frequency in the United States legally. The Federal Communications Commission (FCC) lists down guidelines for using FM transmitters. They will enforce sanctions on persons or organizations who operate without FCC authorization. These sanctions include but are not limited to monetary forfeitures, confiscation of equipment, and criminal penalties.

Applying for an FM frequency license for commercial or non-commercial use that covers a wide range of power is not practical, especially if you only use it for an hour or once a week. Getting a frequency license for your church is a tedious process. It also involves the FCC and Congress.

Unlicensed broadcast, though, is still possible. These rules are covered under part 15 of the rules of the FCC. Part 15 devices are limited to a 200-feet service range. Such a device should not exceed 250 microvolts per meter at three meters. So even if your church does not have an FCC license, the FM transmitter you will use must be FCC approved.

To ensure that you’re using an FM transmitter and broadcasting legally, I recommend that you contact FCC, even if your device has an FCC license, to know if you are permitted to use a particular FM transmitter for your church setup.

Things to Consider When Buying an FM Transmitter for Church


Excellent FM transmitters provide good sound quality, including those with noise cancellation features. Choose an FM transmitter that does not malfunction easily and is built with quality materials. Since there is no guarantee of how long the pandemic protocols will stretch, it is best to invest in an FM transmitter that will last.


FM transmitters have particular frequency ranges. The best frequency range for optimal bandwidth options is 87.5 to 108.0 MHz. These frequencies are for commercial and non-commercial use. The caveat here is to still consider FCC guidelines for broadcasting, especially for low power transmitters, which usually have low power ranges that cover a limited space. Standard low-power FM transmitters range between 500 to 1000 watts.


FM transmitters have varied power sources. Some use batteries, and others use connectors that plug into the car’s cigarette lighter. The latter is a convenient option. 

Make sure that your FM transmitter is matched with the device you’re plugging it into. Not all music players and smartphones are compatible with all FM transmitters. So it is good to buy one with wide compatibility with various devices.

Some FM transmitters also have USB support and are hands-free for ease of use. 


To avoid the risk of sanctions and penalties, make sure that your FM transmitter is approved by the FCC. An authorized device will have an FCC ID number which you can search for and verify in the database of the FCC.


Using an FM transmitter for the church is an affordable way to share the Word of God in this trying time of a global pandemic. Choose an FM transmitter that fits your church’s budget without compromising its quality, integrity, and functionality.
