Some instructions on the firing range:

Factors that affect the transmission range is very large,
For example:
1. Transmitter output power. Of course, exactly the same conditions in other cases, the higher the transmission power, the greater the distance fired.
2. Transmitter antenna height. Because the FM band of electromagnetic waves is the approximate straight lines, and its propagation characteristics and light almost. Then obviously, the higher the antenna, transmitter farther.
3. Transmitter antenna gain. The higher the antenna gain, emission will be farther away from
4. Surrounding environment. Have said earlier, FM band and light propagation characteristics of electromagnetic waves similar, so if the transmitting antenna and receiving antenna have a high building block, then the firing range will also suffer greatly.
5. Receiver sensitivity. Receiver sensitivity is low, then high transmitter power and then not help, it is very obvious reason.
6. Electromagnetic environment. If the adverse electromagnetic environment, of course it will cause interference on the receiver, reception it would certainly be affected. As the two people inside the chat in DISCO, it is quite strenuous.

In summary, the rigid target in the general transmitter and did not launch from the index, the distance from the use of the environment is not realistic to talk about the launch.
However, we can press the ideal environment to provide users with reference to consider the distance:
0.5W———— 1000m
2W ———— 2000m
5W ————- 5000m
10W ————– 6500m
15W ————– 8000m
20W ————- 10000m
30W ————- 13000m
50W ————- 15000m
100W ———— 18000m
500W ———— 40000m

Note:
1. The so-called ideal conditions: the transmitting antenna high enough, and no stop between the receiver antenna. Antenna in good working order. Receiver sensitivity of-90dbm above. There is no electromagnetic interference with the environment.
2. Firing range is for reference only and is not a guarantee.

    Great thinking! That really braeks the mold!
