Hi all today I'm going to give you a Tv transmitter circuit diagram..Actually  Tv transmitters are ban in some countries. So If build this build it with your own risk.Here we have used transistor BC 108.This circuit can be operated with 12V power supply.With out supplying an antenna don't supply power for the circuit.With this circuit diagram you can send signals up to 75 m to 100 m.Try this circuit and have a nice day.
