Simple UHF Video Transmitter circuit and explanation
This video transmitter requires supplies voltage of 9-15 volt. However, you can also use a 9v batteries. Better result on low signal noise, use switching power supply.
This is an important thing to remember for building of the video transmitter circuit is that the dimensions of coil size to match the frequency of the desired work. The value of the spindle is making coil as follows:
L1, L2 = 3 Turns, diam. 3mm, 0.5mm wire
L3 = 2 Turns, diam. 3 mm, 0.5 mm wire

Video Amplifier Circuit Diagram
Video amplifier circuit is simple and can be used. Video amplifier circuit was constructed from 2 pieces of transistors BC550 and BC560. The source voltage used for supplying the video amplifier circuit is 5VDC. Video amplifier circuit is equipped with a powerful regulator which flows through both transistors T1 and T2, the components used to manage these flows are P1 and P2.

Then the video amplifier circuit is also equipped with limiting the maximum current that passes through T1 and T2. The components in black block functions as limiting the maximum current that is passed by the T1 and T2 for no more than 5mA.
