RF Low Pass Filter for FM Transmitters (88-108mhz)

This circuit was designed to be used with any FM Transmitter to greatly reduce or eliminate unwanted harmonics in your transmitted radio frequency. The schematic for 88-108mhz is shown in this video. For other custom frequency ranges, please refer to the online calculator link shown below. Failure to suppress these harmonics, can result in interference in other bands such as aircraft and military, and possibly result in the FCC knocking on your door. In the past I uploaded a video for a 4W and 1W FM transmitter. Both videos did not show a low pass filter in the schematic. To add one(highly suggested), you would simply add this circuit to the RF output of either one of those circuits. ALWAYS transmit on a frequency which is not in use!
