Low power transmitter




This is the 30W transmitter cover range 5-8KM outside.It set for the people who want to build the fm station first time. It is widely used on the meeting ,village broadcasting,Speech ,concert .And also schools,supermarkets, factories, railway stations, conferences. You can build your own station easily.

If you are the dealer who want to resale this transmitters in your country.Please contact Erin Huang.We can give you more suggestion.

About the Antenna:



  1. A dipole antenna is a radio antenna that can be made of aluminum, copper, and bronze  tube  with a center-fed driven element. It consists of two metal conductors of rod, oriented parallel and collinear with each other (in line with each other), with a small space between them.
  2. The dipole antenna is a particularly important form of RF antenna which is very widely used for radio transmitting and receiving applications. The dipole is often used on its own as an RF antenna, but it also forms the essential element in many other types of RF antenna. As such it is the possibly the most important form of RF antenna.
  3. A half-wave dipole antenna means the length of this dipole antenna is equal to a half-wavelength at the frequency of operation.



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 ~15KM

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

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

1KW ~ 2KW FM Transmitter : 50KM ~100KM

2KW ~5KW FM Transmitter : 100KM ~150KM

5KW ~10KW FM Transmitter : 150KM ~200KM
