10-50公里内的无线反车辆发射器和reciver

Remote wireless AV transmitter and reciver ,50KM MICROWAVE WIRELESS VIDEO TRANSMISSION EQUIPMENT Transmission distance up to 50KM PRODUCT OVERVIEWThe series of ST-6300 microwave AV transmitter can transmit AV signals several ten kilometers away form one place to another. The most advanced GASSFET & technology makes the high quality and stability. The very low noise figure makes picture clear and enjoyable. This product covers full band of microwave frequency on request and outdoor use available. The specially designed microwave multicarrier transposes (BK/BK Amplifier) with solar cell systems can resolve the problems of blockness of mountains or other objects.ST-6300 works on FM modulation type (AM type offered on request). Visual and aural signals from camera or other program sources are put into the “Video in ” and “Audio in ” port of the transmitter, they are emitted through the directional or omni-directional antenna. The microwave signals travels several ten kilometers arriving at the receiving point. The microwave receiver changes it back to visual and aural signals. Then a beautiful picture will be obtained on the screen of your monitor. INSTALLATION AND CONNECTIONS1. The RF output port is N-type L 16 or SMA connector, it will be connected with the coaxial cable of 50Ω to the antenna.2. The video input point is F-type connector. It will be connected by the coaxial cable of 75Ω to the video resource such as camera etc.3. The Audio and +12VDC power input point are all in a 4-pin connecter. The “pin 1” is “+12VDC”. “pin 2” is “audio in”, The “pin 3” and “pin 4” are ground point.4.
