Schematic Diagram

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
