This is a TV transmitter for transmitting video of various video sources such as video cameras, Satellite receivers, DVD players, game consoles, etc. TV transmitter’s circuit is working on the 470-580 MHz frequency and can be received on UHF channels 21-34. TV Video transmitter can radiate as far as 300 meters by using a 10-20 cm wire antenna. TV transmitter requires voltage of 9-15 Volts. However, you can also use a 9v batteries. Oscillator is based around BF199 and BFR90 RF transistors. If needed the range of TV transmitter can be extended by replacing BFR90 with 2N3886 transistors.

This is an important thing to remember for building of the TV 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
