    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

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

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

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