Q1:What is FM transmitter? An FM transmitter is a device that can convert audio contents from any audio source such as MP3,Cellphone,Computer etc. to signals that transmits out in FM band, the signals can be picked up by any radio receivers that uses the same frequency at the other end. Q2:How does FM transmitter work? Firstly connect the audio source to FM transmitter, the audio signals will be converted to FM signals and broadcast out through the antenna via tuned frequency, people at the other end use a radio receiver to hear the audio by tuning to the same frequency. Q3:How to choose antenna for transmitter? Usually we need to check the maximum RF power that the antenna can afford, then use the antenna with transmitter that broadcasts at or below the antenna MAX.RF Power. Q4:How many frequencies can I use in one transmitter? Most of our transmitter are in normal FM frequency band(87~108mhz), you can change to any frequency within this band. Use one frequency at one time. |
