How far(long) the transmitter cover?

The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.

EXAMPLE 5W FM Transmitter use in the city and hometown:

I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).

I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).

I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).

Below are the approximate range of different power FM Transmitters. ( The range is diameter )

0.1W ~ 5W FM Transmitter :100M ~1KM

5W ~15W FM Ttransmitter : 1KM ~ 3KM

15W ~ 80W FM Transmitter : 3KM ~10KM

80W ~500W FM Transmitter : 10KM ~30KM

500W ~1000W FM Transmitter : 30KM ~ 50KM




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.
