mini fm transmitter has a range of about 300-400 meters, when using a 9 volt voltage of the power scattered around 300 meters, and when using a voltage of 12 volt then reach around 400-450 meters, depending on the antenna in use.
For L1 and l2 twist it 5 times roll, you can use the pen cartridge to wind it so neat and after the finish remove the contents pen cartridge page. C5 is used for placement frequency. can tune in between 88-108 Mhz, to reach more use referrer antenna (yagi antenna).
