TV transmitter circuit is working on the UHF channell, 470-580 MHz frequency channel 21-34. This transmitter can radiate as far as 30-100 meters by using a cable 10-20 cm.
TV transmitter requires supplies voltage of 9-15 Volt. However, you can also use a 9v batteries.
This is an important thing to remember for building of the tv ransmitter 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
