Note:
* Connect antenna first before connecting transmitter to DC supply, otherwise, transmitter will be burned out.

Some instructions on the FM transmitter cover 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.

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.

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.

A half-wave dipole antenna means the length of this dipole antenna is equal to a half-wavelength at the frequency of operation.

Why do we recommend this dipole antenna?view

1).The half-wave dipole is very clear and easy for frequency adjustation, there are scales on the side bar of the antenna from which you can adjust the frequency from 88~108 by 1mhz stepping.dispole1

 

2).The dipole is a simple antenna to construct and use, and many of the calculations are quite straightforward.IMG_5587

 

 

3.)The radiation pattern and high gain of dipole:

Attention: When setting the antenna, the “Anode” end should be face up, “negetive electrode” should be face down
