112.25－1000MHz TV transmitter 0.25MHz step include broadcast and receive antennas
 This modulator is mainly used for long-distance transmission and short-range wireless broadcast. When use cable transmission, the output connect the transmission cable, So because of higher output and transmission distance is far more than conventional modulator;
When use wireless transmission, the output connect to the transmit antenna, transmission distance depends on the selected transmitting antenna.
Usually, when the frequency arround 400MHz, the semidiameter coverage range is 1km~2km Main technical parameters

How far(long) the transmitter cover? The transmission range depends on many factors. The true distance is based on the sensitivity of the receiver, antenna of the receiver, and the building and other obstructions, which are between the transmitter and receiver. And the distance will much more in countryside. 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).
