Generally speaking, FM transmitter transmission distance and transmitter power, the height of transmitting antenna, the local transmission environment (geographical conditions) related to the general 50W the following transmitter radius within 10 kilometers, 3KW FM transmitter can cover to 60KM.

1, the wireless broadcast coverage radius should be depending on the local situation, the more open terrain, flat area launch distance, hilly and mountainous areas will be reduced emission distance.

2, the principle of selection of transmitter power: The distance from the launch center to the farthest, the intensity of the surrounding obstructions, whether the height of the antenna erected is the highest point around.
